CC   -!- CATALYTIC ACTIVITY: 4-aminobutanoate + 2-oxoglutarate = succinate
CC       semialdehyde + L-glutamate.
CC   -!- CATALYTIC ACTIVITY: (S)-3-amino-2-methylpropanoate + 2-
CC       oxoglutarate = 2-methyl-3-oxopropanoate + L-glutamate.
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC   -!- PATHWAY: Amino-acid degradation; 4-aminobutanoate degradation.
CC   -!- SIMILARITY: Belongs to the class-III pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
