n.
an enzyme that catalyses the transfer of an amino group from an amino acid to an a-keto acid in the process of transamination. Examples include aspartate aminotransferase (AST), which catalyses the transamination of glutamate and oxaloacetate to a-ketoglutarate and aspartate, and alanine aminotransferase (ALT), converting glutamate and pyruvate to a-ketoglutarate and alanine.
