Protein

Diaminobutyrate--2-oxoglutarate transaminase

Gene
ectB, OB0518
Organism
Oceanobacillus iheyensis (strain DSM 14371 / JCM 11309 / KCTC 3954 / HTE831)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes reversively the conversion of L-aspartate beta-semialdehyde (ASA) to L-2,4-diaminobutyrate (DABA) by transamination with L-glutamate By similarity.

Catalytic activityi

L-2,4-diaminobutanoate + 2-oxoglutarate = L-aspartate 4-semialdehyde + L-glutamate.

Cofactori

Pyridoxal phosphate By similarity.
