General annotation (Comments)

Function

Catalyzes the conversion of gamma-aminobutyrate and L-beta-aminoisobutyrate to succinate semialdehyde and methylmalonate semialdehyde, respectively. Can also convert delta-aminovalerate and beta-alanine By similarity.

Catalytic activity

4-aminobutanoate + 2-oxoglutarate = succinate semialdehyde + L-glutamate.

(S)-3-amino-2-methylpropanoate + 2-oxoglutarate = 2-methyl-3-oxopropanoate + L-glutamate.

Cofactor

Pyridoxal phosphate By similarity.

Subunit structure

Homodimer; disulfide-linked By similarity.

Subcellular location

Mitochondrion matrix By similarity.

Sequence similarities

Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
