Reaction: 3-aminobutanoyl-CoA + 2-oxoglutarate = acetoacetyl-CoA + L-glutamate
Other name(s): kat (gene name); acyl-CoA β-transaminase
Systematic name: 3-aminobutanoyl-CoA:2-oxoglutarate aminotransferase
Comments: The enzyme, found in bacteria, is part of a L-lysine degradation pathway. The enzyme is also active with other β-amino compounds such as 3-amino-5-methylhexanoyl-CoA and 3-amino-3-phenylpropanoyl-CoA.
