In enzymology a protein-arginine deiminase (EC 3.5.3.15) is an enzyme that catalyzes a form of post translational modification called arginine de-imination or citrullination:protein L-arginine + H2O protein L-citrulline + NH3Thus the two substrates of this enzyme are protein L-arginine and H2O whereas its two products are protein L-citrulline and NH3.This enzyme belongs to the family of hydrolases those acting on carbon-nitrogen bonds other than peptide bonds specifically in linear amidines.
