<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)... Found on http://www.encyclo.co.uk/local/20973
Type: Term Pronunciation: ă-mē′nō-trans′fĕr-ase Definitions: 1. Enzyme that transfers amino groups from an amino acid to a keto acid, l-alanine and 2-ketoglutarate. Often, the amino acid is an α-amino acid and the keto acid is an α-keto acid. Synonyms: transaminases Found on http://www.medilexicon.com/medicaldictionary.php?t=2867
Aminotransferase: An enzyme that catalyzes the transfer of an amino group from a donor molecule to a recipient molecule. The donor molecule is usually an amino acid while the recipient (acceptor) molecule is usually an alpha-2 keto acid. An aminotransferase is also called a transaminase. Two of the better known enzymes in this class are serum gluta... Found on http://www.medterms.com/script/main/art.asp?articlekey=6591
