ID 3.5.1.94 DE gamma-glutamyl-gamma-aminobutyrate hydrolase. AN gamma-glutamyl-GABA hydrolase. CA 4-(gamma-L-glutamylamino)butanoate + H2O = 4-aminobutanoate + CA L-glutamate. CC -!- Forms part of a novel putrescine-utilizing pathway in Escherichia CC coli, in which it has been hypothesized that putrescine is first CC glutamylated to form gamma-glutamylputrescine, which is oxidized to CC 4-(gamma-glutamylamino)butanal and then to 4-(gamma- CC glutamylamino)butanoate. CC -!- Also can catalyze the reactions of EC 3.5.1.35 and EC 3.5.1.65. DR Q8X7G2, PUUD_ECO57 ; P76038, PUUD_ECOLI ; Q83LB6, PUUD_SHIFL ; DR Q3Z146, PUUD_SHISS ; //
