Protein attributes

Sequence length	509 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Deaminates gamma-aminobutyric acid (GABA) to succinate-semialdehyde, which in turn is converted to succinate by the succinate semialdehyde dehydrogenase By similarity. Not required for the utilization of GABA as nitrogen source. Ref.1
Catalytic activity	4-aminobutanoate + 2-oxoglutarate = succinate semialdehyde + L-glutamate.
Cofactor	Pyridoxal phosphate.
Subunit structure	Homodimer By similarity.
Subcellular location	Cytoplasm By similarity.
Induction	Up-regulated by GABA and beta-alanine. Is not subject to nitrogen catabolite repression. Ref.1
Sequence similarities	Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
