| creatinase M-CSA #96 | Creatinase or creatine amidinohydrolase (EC:3.5.3.3) catalyses the conversion of creatine and water to sarcosine and urea. This is a key step in the metabolic breakdown of creatinine by micro-organisms. Creatinase is also found in higher animals but its metabolic role is as yet not known. | Defined by 3 residues: HIS:A-231 [auth A-232]GLU:A-261 [auth A-262]GLU:A-357 [auth A-358] | EC: 3.5.3.3 (PDB Primary Data) |
