|---|---|
| alpha-fucosidase | <enzyme> An enzyme that catalyses the hydrolysis of an an alpha-l-fucoside, producing an alcohol and l-fucose; a deficiency of the lysosomal enzyme will result in fucosidosis. (05 Mar 2000) |
| alpha-galactosidase | <enzyme> An enzyme that catalyses the hydrolysis of terminal, non-reducing alpha-d-galactose residues in alpha-galactosides including galactose oligosaccharides, galactomannans, and galactolipids. Chemical name: alpha-D-Galactoside galactohydrolase Registry number: EC 3.2.1.22 (12 Dec 1998) |
| alpha-globulin | <protein> The serum globulins with the most rapid electrophoretic migration, further subdivided into faster alpha(1)- and slower alpha(2)-globulins. (12 Dec 1998) |
| alpha-glucan branching glycosyltransferase | 1,4-alpha-d-glucan branching enzyme |
| 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-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-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.
