creatininase  M-CSA #720

Creatininase (creatinine amidohydrolase) from Pseudomonas putida catalyses the conversion of creatinine to creatine. It is a member of the urease-related amidohydrolase superfamily. The enzyme enables the bacteria to use creatinine as a source of carbon and nitrogen. The biological molecule is trimer of dimers. The active site of each monomer contains a binuclear metal centre located at the bottom of a cleft. In the native form of the enzyme both metal sites are occupied by Zn2+ ions.
