| alpha-glucan phosphorylase | <enzyme> Enzyme that catalyses the sequential removal of glycosyl residues from glycogen to yield one glucose-1-phosphate per reaction. Its activity is controlled by phosphorylation (by phosphorylase kinase). (21 Jun 2000) |
|---|---|
| alpha glucosidase | <enzyme> An enzyme which removes the last 1,4-linked alpha-D-glucose residue from the nonreducing end of a long chain (or polymer) of such residues, making an alpha-D-glucose molecule out of it in the process. (09 Oct 1997) |
| alpha-glucosidases | <enzyme> Enzymes that catalyze the exohydrolysis of 1,4-alpha-glucosidic linkages with release of alpha-glucose. Chemical name: alpha-D-Glucoside glucohydrolases Registry number: EC 3.2.1.20 (12 Dec 1998) |
| alpha granule | A granule of an alpha cell that was named as the first of several kinds or because it was acidophilic. (05 Mar 2000) |
| alpha helix | <molecular biology> A particular helical folding of the polypeptide backbone in protein molecules (both fibrous and globular), in which the carbonyl oxygens are all hydrogen bonded to amide nitrogen atoms three residues along the chain. The translation of amino acid residues along the long axis is 0.15 nm and the rotation per residue, 100 |
| alpha-hydroxyethylthiamin pyrophosphate | The activated form of acetaldehyde that is formed during the decarboxylation of active pyruvate. Formed in alcohol fermentation and in carbohydrate metabolism. Synonym: a-hydroxyethylthiamin pyrophosphate. (05 Mar 2000) |
| alpha-hydroxyglycine amidating dealkylase | <enzyme> From bovine neurointermediate pituitary; catalyses the conversion of alpha-hydroxybenzoylglycine to benzamide and glycolytic acid Registry number: EC 1.14.99.- Synonym: hgad-ase (26 Jun 1999) |
| alpha interferon | <cytokine> Interferon which is released by leukocytes in response to a viral infection. A protein cytokine that is used as an anticancer agent. (15 Nov 1997) |
| alpha-keto acid dehydrogenase | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase. (05 Mar 2000) |
| alpha-keto acid dehydrogenase complex | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase. (05 Mar 2000) |

| alpha-ketodecarboxylase | Formerly, the enzyme system converting pyruvate (a 2-oxoacid) to acetyl-CoA and CO2, with reduction of NAD+ to NADH and the participation of lipoamide and thiamin pyrophosphate; now known to involve at least three enzymes in succession: pyruvate dehydrogenase, dihydrolipoamide acetyltransferase, and dihydrolipoamide dehydrogenase. Compare: pyruvate dehydrogenase (lipoamide). (05 Mar 2000) |
| alpha-ketoglutaramic acid | H2N-COCH2CH2COCOOH;a metabolite of glutamine formed by the action of glutamine aminotransferase; elevated in certain cases of hepatocoma. Synonym: 2-oxoglutaric acid. (05 Mar 2000) |
