IUBMB Enzyme Nomenclature

EC 3.5.1.123

Accepted name: γ-glutamylanilide hydrolase

Reaction: N5-phenyl-L-glutamine + H2O = L-glutamate + aniline

Glossary: γ-glutamylanilide = N5-phenyl-L-glutamine

Other name(s): atdA2 (gene name)

Systematic name: N5-phenyl-L-glutamine amidohydrolase

Comments: The enzyme, characterized from the bacterium Acinetobacter sp. YAA, catalyses the opposite reaction from that cayalysed by EC 6.3.1.18, γ-glutamylanilide synthase, which is part of an aniline degradation pathway. Its purpose is likely to maintain a low concentration of N5-phenyl-L-glutamine, which is potentially toxic.
