This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is (R)-3-amino-2-methylpropanoate:pyruvate aminotransferase. Other names in common use include D-3-aminoisobutyrate-pyruvate transaminase, beta-aminoisobutyrate-pyruvate aminotransferase, D-3-aminoisobutyrate-pyruvate aminotransferase, D-3-aminoisobutyrate-pyruvate transaminase, (R)-3-amino-2-methylpropionate transaminase, and D-beta-aminoisobutyrate:pyruvate aminotransferase.
