| aminosalicylic acids | Amino-2-hydroxybenzoic acids. A group of hydroxybenzoic acids that include substitution by amino groups at the 3-, 4-, 5-, or 6-position. The 4-amino derivative, p-aminosalicylic acid, is an antitubercular agent. (12 Dec 1998) |
| aminotransferase | <enzyme> A family of enzymes that catalyse the transfer of an amino group from an alpha-amino acid to an alpha-keto acid, as in the transfer from glutamic acid to oxaloacetic acid, to form aspartic acid and alpha ketoglutarate. One reactant is often glutamic acid and the reactions employ pyridoxal phosphate as co-enzyme. (04 May 1997) |
| aminotransferases | Enzymes transferring amino groups between an amino acid to (usually) a 2-keto acid; e.g., l-alanine and 2-ketoglutarate. Often, the amino acid is an alpha-amino acid. Synonym: aminopherases, transaminases. (05 Mar 2000) |
