DAB aminotransferase.
DABA aminotransferase.
Diaminibutyric acid aminotransferase.
Diaminobutyrate transaminase.
Diaminobutyrate--2-oxoglutarate aminotransferase.
Reaction catalysed
L-2,4-diaminobutanoate + 2-oxoglutarate <=> L-aspartate 4-semialdehyde + L-glutamate

Comment(s)
  • Differs from EC 2.6.1.46, which has pyruvate as the amino-group acceptor.
