Chain A ( ODPA_HUMAN | P08559)
| molecular function |
|---|
| | GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| | GO:0016624 | | oxidoreductase activity, acting on the aldehyde or oxo group of donors, disulfide as acceptor | | Catalysis of an oxidation-reduction (redox) reaction in which an aldehyde or ketone (oxo) group acts as a hydrogen or electron donor and reduces a disulfide. |
| | GO:0034604 | | pyruvate dehydrogenase (NAD+) activity | | Catalysis of the reaction: pyruvate + CoA + NAD+ = acetyl-CoA + CO2 + NADH. |
| | GO:0004739 | | pyruvate dehydrogenase (acetyl-transferring) activity | | Catalysis of the reaction: pyruvate + lipoamide = S-acetyldihydrolipoamide + CO2. |
| | GO:0004738 | | pyruvate dehydrogenase activity | | Catalysis of the oxidative decarboxylation of pyruvate. |
| biological process |
|---|
| | GO:0006086 | | acetyl-CoA biosynthetic process from pyruvate | | The chemical reactions and pathways resulting in the formation of acetyl-CoA from pyruvate. |
| | GO:0005975 | | carbohydrate metabolic process | | The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. |
| | GO:0006006 | | glucose metabolic process | | The chemical reactions and pathways involving glucose, the aldohexose gluco-hexose. D-glucose is dextrorotatory and is sometimes known as dextrose; it is an important source of energy for living organisms and is found free as well as combined in homo- and hetero-oligosaccharides and polysaccharides. |
| | GO:0046487 | | glyoxylate metabolic process | | The chemical reactions and pathways involving glyoxylate, the anion of glyoxylic acid, HOC-COOH. |
| | GO:0008152 | | metabolic process | | The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
| | GO:0061732 | | mitochondrial acetyl-CoA biosynthetic process from pyruvate | | The chemical reactions and pathways resulting in the formation of acetyl-CoA from pyruvate in the mitochondrion. The process begins with the transport of pyruvate from the cytosol to the mitochondrion where it is subsequently decarboxylated to form acetyl-CoA. |
| | GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| | GO:0006090 | | pyruvate metabolic process | | The chemical reactions and pathways involving pyruvate, 2-oxopropanoate. |
| | GO:0010510 | | regulation of acetyl-CoA biosynthetic process from pyruvate | | Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of acetyl-CoA from pyruvate. |
| | GO:0006099 | | tricarboxylic acid cycle | | A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two CO2 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle. |

| | GO:0005759 | | mitochondrial matrix | | The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. |
| | GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
| | GO:0043209 | | myelin sheath | | An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. |
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
| | GO:0045254 | | pyruvate dehydrogenase complex | | Complex that carries out the oxidative decarboxylation of pyruvate to form acetyl-CoA; comprises subunits possessing three catalytic activities: pyruvate dehydrogenase (E1), dihydrolipoamide S-acetyltransferase (E2), and dihydrolipoamide dehydrogenase (E3). |
