Acting on phosphorus-nitrogen bonds;
Acting on phosphorus-nitrogen bonds (only sub-subclass identified to date)
BRITE hierarchy
Sysname
phosphamide hydrolase
Reaction(IUBMB)
N-phosphocreatine + H2O = creatine + phosphate [RN:R01882]
Reaction(KEGG)
Substrate
N-phosphocreatine [CPD:C02305];
H2O [CPD:C00001]
Product
creatine [CPD:C00300];
phosphate [CPD:C00009]
Comment
Also acts on N-phospho-arginine and other phosphoamides. Possibly identical with EC 3.1.3.9 (glucose-6-phosphatase) or EC 3.1.3.16 (protein-serine/threonine phosphatase).
