Arginine deiminase uses an active-site cysteine in nucleophilic catalysis of L-arginine hydrolysis.


Arginine deiminase (EC catalyzes the hydrolysis of l-arginine to citrulline and ammonium ion, which is the first step of the microbial l-arginine degradation pathway. The deiminase conserves the active-site Cys-His-Asp motif found in several related enzymes that catalyze group-transfer reactions from the guanidinium center of arginine-containing… (More)
