2.6.1.40
Description (R)-3-amino-2-methylpropionate--pyruvate aminotransferase.
Alternative names D-3-aminoisobutyrate--pyruvate aminotransferase;
Beta-aminoisobutyrate--pyruvate transaminase.
Catalyzed reaction (R)-3-amino-2-methylpropanoate + pyruvate = 2-methyl-3-oxopropanoate + L-alanine.
Cofactor Pyridoxal-phosphate.
The enzyme from rat liver appears to be identical to Alanine--glyoxylate aminotransferase (2.6.1.44), isoenzyme 2.
