  • Glycogen Metabolism II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu In the notes below, I refer to Glycogen Phosphorylase a as GPa and Glycogen Phosphorylase b as GPb. I also refer to Glycogen Synthase a as GSa and Glycogen Synthase b as GSb. You are welcome to do the same. 1. Glycogen phosphorylase is present in two forms, GPa and GPb. They differ in phosphorylation. GPa is phosphorylated and GPb is not.1. GPb is converted into GPa by phosphorylation at two sites. Covalent modifications are DIFFERENT from allosteric controls, which interconvert the R and T states of BOTH GPa and GPb. 2. 9. Thus, the binding of epinephrine to the cell surface stimulates the following events in muscle relating to glycogen breakdown A. Epinephrine binds receptor B. Receptor activates a G protein to bind GTP C. Alpha subunit of G protein activates adenylate cyclase D. Adenylate cyclase catalyzes formation of cAMP E. cAMP activates protein kinase A F. Protein kinase A phosphorylates phosphorylase kinase, activating it. G. Phosphorylase kinase phosphorylates GPb, converting it to GPa H. GPa breaks down glycogen to yield G1P 10. Glycogen synthase, like glycogen phosphorylase, is regulated at least partially by phosphorylation. Note that GSa has NO PHOSPHATE whereas GSb HAS PHOSPHATE. You should know the function/activites of the enzymes in glycogen synthesis - phosphoglucomutase ...
  • Glycolysis I This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Glycolysis, the breakdown of glucose, is a catabolic pathway involving oxidation and yields ATP energy. Gluconeogenesis, the synthesis of glucose, is an anabolic pathway that involves reduction and requires ATP and ATP.. There are 10 reactions in glycolysis. Students should know structures of fructose and glucose compounds, glyceraldehyde-3-phosphate, 1,3 BPG, all enzyme names, all molecule names, and reactions I described where the Delta G zero prime is strongly positive, or strongly negative. 2. Note that glycolysis has three phases - an energy investment phase, a molecular rearrangement phase, and an energy realization phase where ATP is made. 3. In reaction #1 of glycolysis, hexokinase catalyzes transfer of phosphate to glucose from ATP, forming G6P. Thus, this step uses ATP, which provides the energy necessary for the reaction to proceed. It is an example of an energy-coupled reaction and the Delta G zero prime is strongly negative, thanks to the ATP hydrolysis. 4. Hexokinase changes shape as it binds to glucose. This property is consistent with that of an induced fit of an enzyme in the process of catalysis. 5. Reaction #2 of glycolysis is catalyzed by phosphoglucoisomerase. In it, G6P is converted to F6P. The Delta G zero prime for the reaction is close to zero. Note than a linear ...

  • Fatty Acid Oxidation This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Fats are broken down to fatty acids and glycerol by enzymes known as lipases. One of these, hormone sensitive triacylglycerol lipase, is the only regulated enzyme of fat or fatty acid breakdown. It is located in fat-storing cells called adipocytes. 2. Triacylglycerol lipase action cleaves the first fatty acid off of a fat and this step is necessary before the other lipase can act to remove the other fatty acids from a fat. 3. Glycerol, is the only part of a fat that can be made into glucose (via gluconeogenesis). Fatty acids travel in the bloodstream carried by serum albumin. 4. Fatty acid oxidation occurs in the matrix of the mitochondrion. In the cell, fatty acids are attached to CoA and then at the mitochondrion, the CoA is replaced by carnitine. Inside the mitochondrial matrix, the carnitine is replace by CoA again. 5. Steps in fatty acid oxidation include dehydrogenation, hydration, oxidation, and thiolytic cleavage. The dehydrogenation and oxidation reactions yield reduced electron carriers (FADH2 and NADH). The double bond formed in the first dehydrogenation reaction is in the trans form. The hydration yields a hydroxyl group on the third carbon from CoA end in the "L" configuration. Thiolytic cleavage is catalyzed by the enzyme called thiolase. Two enzymes you should know include acyl ...
  • Elders in Ritual Space, Elders Light Up When I am Real Earlier Steven talked about the three areas that an Elder shows up in. One is Family, Second is culture, This third area is ritual space, a gateway to the other world. The Elder is about Being not doing. Practice being an elder in front of others. Mens work started out in honoring authenticity. We are all equal in sacred space and in initiation. Seeing things as they are. Practice detecting the real. The mentor catalyzes what I came here to do. The Elder catalyzes who I came here to be. Elder scans for realness and lights up. It is hard to be real. My soul wants the truth. My head feeds on thoughts My heart feeds on emotions. My soul feeds on the truth. Practice my practice to be real. Exercises you can do. My persona is a shield that protects me, but keeps me from being real The culture gives elders a pass, free to be vigilant for truth. We are watching something. Elder doesn't have to watch that. Looks and listens to other things.. Exercise: Listen to all the sounds. Coming into the present is coming into sensation. "Who is here with me now?" There is stuff here that I am not aware of, like the grandfathers coming in.
  • Fatty acids transport www.carnitinaofficialsite.it Carnitine carries out an essential role in the transport of long chain fatty acids through the inner mitochondrial membrane. This membrane is otherwise impermeable to long chain fatty acids (≥ C12) and is only through Carnitine that they can cross the inner mitochondrial membrane in order to be beta-oxidised in the matrix. Beta-oxidation produces acetyl groups, which when activated in the form of acetyl- CoA (acetyl coenzyme A) enter the Krebs cycle participating in energy production in the form of ATP (adenosine triphosphate). The transport of long chain fatty acids within the mitochondria takes place with the help of three enzymes: 1. CPT I (Carnitine palmitoyltransferase I), located on the outer mitochondrial membrane, it catalyses the following reaction: CPT I acyl-CoA + Carnitine → acil-Carnitine + CoA 2. CT (Carnitine-acylcarnitine translocase), located on the inner mitochondrial membrane, exchanges free carnitine present in the mitochondrial matrix with acylcarnitine present in the cytoplasm and exports acetylcarnitine from the mitochondrial matrix to the cytoplasm. 3. CPT II (Carnitine palmitoyltransferase II), located on the inner mitochondrial membrane, catalyzes the following reaction: CPT II acil-Carnitine + CoA → acyl-CoA + Carnitine Detoxification of potentially toxic metabolites
  • HCV Life Cycle Hepatitis-C Virus (HCV) belongs to the Flaviviridae family and is the leading cause of chronic liver disease globally. In order to carry out its life cycle hepatitis C virus must attach to and infect liver cells. The entry of HCV into the hepatocyte begins with receptor-mediated endocytosis, in which a cell internalizes a ligand-bound surface receptor. Once released inside the cell, single stranded HCV RNA is used as a blueprint for the production of viral proteins. The primary product of HCV translation is a single polyprotein which contains all ten HCV structural and nonstructural proteins required for HCV replication. This polyprotein is cleaved, or sliced up to produce structural proteins (capsid protein C, E1, E2 and p7), and nonstructural proteins (NS2, NS3, NS4A, NS4B, NS5A and NS5B), in order for the viral proteins to function properly. NS5B protein, which is the RdRp (RNA-dependent RNA polymerase) catalyzes the replication of HCV RNA. The new positive-sense HCV RNA is encapsidated with the structural proteins, known as the nucleocapsid, which is presumably enveloped by budding into the lumen of the ER. Finally, infectious virions are then transported through the Golgi compartment to the plasma membrane and released to infect new cells. HCV does not kill the cells it infects, but triggers an immune mediated inflammatory response (Hepatitis) that either rapidly clears the infection or slowly destroys the liver, causing the development of hepatocellular carcinoma ...

  • Interview with Ariel Spilsbury - 2 of 2 What is sacred theater? In Greek culture, sacred theater was called Therapia (the work of the gods) because it was considered to be a form of engaging conscious evolution of the soul through ecstatic attunement. It was a sacred medium in which to gather to honor the growing seeds of consciousness. It was a sanctified forum in which to heal, to celebrate, to go to the highest possible denominator together in ecstasy. It explored the mythic, archetypal dimensions of being that actually set and guided the field for our egos to play out the mythic scripting of our soul's evolution. It opened the field to more mythic expressions of the masks of Self, than our ego's may have been previously aware. The ancients knew what we have forgotten, that archetypal energy heals, catalyzes and transforms beyond the mind's ability to cognize. Sacred Theater provides the container for that archetypal transaction to take place. Who is Ariel and The Divine Cosmic Circus? Ariel is the author of The Mayan Oracle, & The 13 Moon Oracle: Holographic Meditations on the Mystery.

  • Enzymes II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. The Gibbs free energy is the energy available to do useful work in reactions. The change in the Gibbs free energy for a reaction is important because it determines whether a reaction is favored, unfavored, or at equilibrium. 2. Thus, when the Gibbs free energy change is negative, the reaction in question goes forward as written, but when the Gibbs free energy change is positive, the reaction goes in reverse. 3. A related term to G is G°', which is the Standard Gibbs Free Energy change. This refers to the Gibbs Free Energy change for a reaction under standard conditions. Since most reactions occur at non-standard conditions, G is much more useful than G°'. In fact, the sign of G°' does NOT tell the direction of a reaction, except under standard conditions. 4. Chemical reactions require activation energy (I'll call it G+ here) in order to get started. Catalysts (both enzymes and non-biological catalysts) act by lowering G+. Catalysts DO NOT CHANGE G. All they do is lower the energy required to activate the reaction. While enzymes speed reactions immensely, they therefore DO NOT CHANGE THE OVERALL REACTION CONCENTRATION AT EQUILIBRIUM. They simply allow the reaction to get to equilibrium faster. 5. G is affected by the concentration of reactants and products of a reaction by the following equation ...
  • Hydrochloric Acid (HCl) Production In The Stomach Animation This is a quick animation of how HCl is produced in the stomach. So this was extra credit for a class and I didn't have much time to go more in detail. I apologize for any errors that the animation might have. I also included what I was saying, because I know some people learn better if they are able to read it. Hydrochloric Acid Production in the cell •In order to protect the cells from the damaging acidity of hydrochloric acid, the parietal cell has to produce the components of HCl separately. •Histamine, Gastrin, and ACh will bind to receptors on the parietal cell. This initiates the HCl production process. All three chemicals have to bind to cell in order for this process to occur, otherwise hydrochloric production won't happen. •Carbon dioxide diffuses into the cell, and the enzyme carbonic anhydrase catalyzes the reaction between carbon dioxide and water to form carbonic acid. •Carbonic acid dissociates into bicarbonate ion and hydrogen ion. As the bicarbonate ion accumulates into the cell, bicarbonate ion is ejected through the basal cell membrane into the capillary blood. As a result, blood draining from the stomach is more alkaline than the blood serving it, this is known as the alkaline tide. •The bicarbonate/chloride antiporter in the plasma membrane exchanges bicarbonate molecules going out for chloride ions coming in. This is known as a chloride shift. •ATP will bind to the hydrogen/potassium ATPase, where potassium ions are counter transported into the ...
  • Molecular Mechanism of ATP synthesis.wmv F1Fo-ATP synthase catalyzes the final step of oxidative phosphorylation, the synthesis of ATP from ADP and phosphate, driven by a transmembrane proton gradient. In bacteria, under certain physiological conditions, the enzyme can also hydrolyze ATP to generate a proton gradient. ATP synthesis/hydrolysis and proton translocation are coupled in a unique way, via subunit rotation. While our knowledge of the molecular basis of ATP hydrolysis and its integration with rotation is still far from complete, it is much better understood than ADP phosphorylation because it is easier experimentally accessible

  • Fatty Acid Synthesis This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. The process occurs similar to beta-oxidation, though in reverse. Important distinctions are noted below in af. * a. Fatty acid synthesis up to palmitate occurs in the cytoplasm, but beta oxidation occurs in mitochondrial matrix. * b. Fatty acids are built using an acyl carrier protein (ACP), but beta oxidation uses CoA. * c. NADPH is used to donate electrons in synthesis, but NAD+ or FAD are used to accept electrons in oxidation in the mitochondrion. * d. A three carbon molecule, malonyl-ACP donates two carbons to the growing fatty acid chain - a carbon dioxide is lost in the process. Beta oxidations yield two carbon acetyl-CoA units. * e. Synthesis of fatty acids longer than 16 carbons occurs in endoplasmic reticulum or mitochondrion. Oxidation of fatty acids longer than 16 carbons begins in peroxisomes. * f. In fatty acid biosynthesis, a D-hydroxyl intermediate is formed at carbon #3. In fatty acid oxidation, an L-hydroxyl intermediate is formed at carbon #3. 2. Acetyl-CoA carboxylase catalyzes the addition of a carboxyl group to acetyl-CoA to form malonyl-CoA. The enzyme is regulated allosterically (inhibited by palmitoyl-CoA and activated by citrate) and by covalent modification (phosphorylation inhibits, dephosphorylation activates). 3. Fatty acid biosynthesis occurs in the cytoplasm and ...

  • Allostery and Regulation I This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Aspartate transcarbamoylase (ATCase) is an enzyme that catalyzes the first step in pyrimidine biosynthesis (aspartate + carbamoyl phosphate N-carbamoylaspartate). This enzyme is allosterically regulated in both a positive and negative fashion and also responds to the binding of the substrate (aspartate) to it. 2. CTP, the end product of pyrimidine biosynthesis, inhibits the enzyme,whereas ATP (a purine and an indicator of high energy) activates the enzyme. This phenomenon - where the end product of a metabolic pathway inhibits the first enzyme in the pathway - is known as feedback inhibition. Feedback inhibtion is mediated allosterically - when a small molecule binds to a protein and affects the protein's activity. 3. ATCase has 12 subunits - 6 catalytic and 6 regulatory. The smaller regulatory subunits bind CTP, but not the catalytic subunits. 4. Binding of CTP to the regulatory subunits of ATCase causes the enzyme to stabilize (lock) in the T state (tight, less reactive state). In the T state, the quaternary structure of the enzyme the enzyme exhibits reduced affinity for substrate. In the opposite state, the R state (relaxed state, more reactive state), the enzyme has increased activity and a higher affinity for substrate. ATP stabilizes the R state of the enzyme. 5. In the absence of ATP ...

  • Transcription II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. The factor involved in factor dependent transcription termination in E. coli is called rho. It binds to the 5' end of an RNA being made and (using ATP energy) "climbs" the RNA until it reaches the RNA polymerase. There it destabilizes the RNA/DNA duplex, favoring the release of the RNA polymerase from the DNA and the RNA from the DNA, as well. 2. In prokaryotes, tRNAs are the most altered (processed) RNAs. Modifications start with their being cleaved from a larger RNA containing both tRNAs and rRNAs. Ribonuclease P is a ribozyme (catalytic RNA) that cleaves the 5' end of tRNAs from the larger RNA. Ribonuclease III catalyzes excision of rRNAs from the larger molecule. 3. Eukaryotes and prokaryotes differ significantly in the relationship between transcription and translation. Prokaryotes have no nucleus. In them, translation starts oftentimes WHILE a message is being transcribed. There are no significant modifications to mRNAs in prokaryotes. 4. In eukaryotes, transcription and translation are spacially separated. Transcription occurs in the nucleus, whereas translation occurs in the cytoplasm. In addition, eukaryotic mRNAs are modified at the 5' end (capping), the 3' end (polyadenylation) and even in the middle (editing and splicing). 5. Eukaryotes have 3 specialized RNA polymerases. They ...
  • Rosemary Puhr - Botany 2010 Evolution of the YUCCA-like flavin monooxygenase SPARSE INFLORESCENCE1 lineage within flowering plants. Co-author: Simon Malcomber The phytohormone auxin is known to regulate many aspects of plant development and is essential for the growth of all lateral structures. The YUCCA family of flavin monooxygenase (FMO) genes catalyzes one of the main pathways in the production of the auxin, indole acetic acid (IAA). One YUCCA gene, SPARSE INFLORESCENCE1 (SPI1), has been shown to regulate inflorescence branching in maize, but the SPI1 ortholog in rice, OsYUC1/SPI1, is reported not to have an obvious inflorescence phenotype suggesting that SPI1 function may have diversified within the grass family. Previous phylogenetic ***yses have identified a monocot specific clade of SPI1 genes, but our ***ysis of 182 YUCCA-like FMO genes provides weak support for a eudicot and monocot SPI1 clade that also includes the Arabidopsis YUCCA1 and YUCCA4 genes, plus the tomato and petunia FLOOZY genes. Genomic ***yses will be presented to investigate evidence of conservation of gene synteny in chromosomal regions surrounding SPI1 co-orthologs, and comparative ***yses of SPI1 expression in diverse plant taxa will be presented to investigate the extent of expression diversification. Together these data will provide new insights into the evolution of YUCCA genes and their possible role in driving the diversification of plant morphological form.

  • Catalytic Strategies This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Proteases catalyze the hydrolysis of peptide bonds in polypeptides. They are usually fairly specific for certain amino acids and cut at or near those amino acids. 2. Chymotrypsin is a protease whose activity has been closely studied. Conveniently, the activity of chymotrypsin can be studied using an artificial substrate which, when cleaved by the enzyme, releases a yellow product. 3. When the release of the colored substrate by the enzyme is studied, it appears to occur in two different rates. First there is a VERY rapid release of the colored substrate. After that initial burst of activity, the remaining yellow color is released slowly. 4. The reason appears to be that the reaction catalyzed occurs in two steps. The first step cleaves the bond to produce the yellow product. The product of this release is that the remainder of the substrate is covalently linked to the enzyme. In order for the enzyme to bind another substrate molecule and release more yellow color, it must first release the covalently bound molecule. This step occurs slowly and explains why subsequent yellow molecules are released slowly - after the initial one is released, the enzyme must remove the covalently bound molecule, bind a new substrate, and cut the substrate and the continue the process repeatedly. 5. Chymotrypsin is ...
  • At Play At Play (5.00min) is a short film that deals with ideas of self-awareness, psychological development, technology and identity, and childhood nostalgia. In the sand pit of a rural playschool, a cocooned microcosmic society of children has been infiltrated by a strange new technology. The wing monitor panel of a hand-held DV camera has been fully rotated to create a sort of electronic mirror. This intrusion catalyzes the children's curiosity and begins the development of an awareness of themselves as objective entities experiencing life contained within a form. I started working in KCDC as soon as I finished school myself. It was a Waldorf/Steiner school on the East Coast of Ireland that existed as a utopian environment for children to develop under holistic principals in a beautiful rural landscape. The staff lived together near the grounds and many of the children's families moved from towns and cities to be closer to the project. I was part of this community for the last year of its legacy until a dramatic closure in 2004. The footage in this film constitutes part of a commission by the head of the school to document the daily lives of the children in the centre before its disintegration. It is impossible for me to view this work without considering the circumstances in which it was filmed. Many of these children were ejected into traditional educational systems entirely opposed to the tragically naïve ethos of KCDC. For me, this gives the piece a deeper resonance. Part ...
  • Ribose Tetraacetate It is interesting to note that in this reaction, the hydroxyl group on the number one carbon of ribose is in the alpha position, yet the acetyl group in the ribose tetraacetate is in the beta position. This inversion of configuration between reactant and product is catalyzed by the addition of sodium acetate. With sodium acetate, a basic catalyst, the beta tetraacetate predominates because sodium acetate catalyzes the interconversion of alpha and beta ribose, but not the tetraacetates, and the rate of acetylation of beta ribose is much faster than that of the alpha isomer.
  • Nucleotide Metabolism II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. Ribonucleotide reductase (RNR) catalyzes the formation of deoxyribonucleotides from ribonucleotides. The substrates are ribonucleoside diphosphates (ADP, GDP, CDP, or UDP) and the products are deoxyribonucleoside diphosphates (dADP, dGDP, dCDP, or dUDP). 2. RNR has two pairs of two identical subunits - R1 (large subunit) and R2 (small subunit). R1 has two allosteric binding sites and the active site of the enzyme. R2 forms a tyrosine radical necessary for the reaction mechanism of the enzyme. 3. Ribonucleotide reductase is allosterically regulated via two binding sites - a specificity () binding site (controls which substrates the enzyme binds and which deoxyribonucleotides are made) and an activity binding site (controls whether or not enzyme is active - ATP activates, dATP inactivates). Specificity sites act in a generally complementary fashion. Binding of deoxypyrimidine triphosphates to the specificity site tends to inhibit binding and reduction of pyrimidine diphosphates at the enzyme's active site and stimulates binding and reduction of purine diphosphates at the active site. Binding of deoxypurine triphosphates tends to inhibit reduction of purine diphosphates and stimulates reduction of pyrimidine diphosphates. Don't confuse the active site with the activity site. The ACTIVE SITE is ...

  • Citric Acid Cycle II This course is part of a series taught by Kevin Ahern at Oregon State University on General Biochemistry. For more information about online courses go to ecampus.oregonstate.edu 1. The citric acid cycle consists of two main parts - release of CO2 (first part) and conversion to oxaloacetate (second part). You are responsible for the structures of molecules in the citric acid cycle and the names of the enzymes. 2. In the "first" reaction of the citric acid cycle, citrate synthase catalyzes the joining of the acetyl group from acetyl-CoA to oxaloacetate to make citrate. This reaction is VERY energetically favorable, due to breaking of the thioester bond in acetyl-CoA. The energetically favorable reaction helps to "pull" the relatively unfavorable reaction preceding it. 3. Aconitase catalyzes the rearrangement of citrate to isocitrate. For your information - Aconitase is inhibited by fluorocitrate. Fluoroacetate is a poison that can be used by citrate synthase to make fluorocitrate. 4. The first decarboxylation of the citric acid cycle is catalyzed by isocitrate dehydrogenase and the reaction is strongly favored to the right. The products of this reaction are NADH and alpha ketoglutarate. 5. Alpha ketoglutarate is an important intermediate for its involvement in anapl*** reactions related to transamination (we'll talk about these later). The mechanism of the enzyme acting on alpha ketoglutarate (alpha ketoglutarate dehydrogenase complex) is virtually identical to the ...
