LITERATURE
D253K
-
the mutant enzyme is unable to hydrolyze hippuryl-Arg. Activity with hippuryl-Glu and hippuryl-Asp, this activity is reduced hundred-fold compared with the native enzyme with hippuryl-Arg as substrate
D253R
-
the mutant enzyme is unable to hydrolyze hippuryl-Arg. Activity with hippuryl-Glu and hippuryl-Asp, this activity is reduced hundred-fold compared with the native enzyme with hippuryl-Arg as substrate
G251T/D253K
-
the mutant enzyme is unable to hydrolyze hippuryl-Arg. 100times more active against hippuryl-L-Glu as substrate than the single mutant D253K
