This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is (S)-3-amino-2-methylpropanoate:2-oxoglutarate aminotransferase. Other names in common use include L-3-aminoisobutyrate transaminase, beta-aminobutyric transaminase, L-3-aminoisobutyric aminotransferase, and beta-aminoisobutyrate-alpha-ketoglutarate transaminase. This enzyme participates in valine, leucine and isoleucine degradation.
