  IntEnz view ENZYME view

IntEnz Enzyme Nomenclature


Accepted name:
carbamate kinase
Other names:
carbamoyl phosphokinase
carbamyl phosphokinase
Systematic name:
ATP:carbamate phosphotransferase



The enzyme catalyses the reversible conversion of carbamoyl phosphate and ADP to ATP and carbamate, which hydrolyses to ammonia and hydrogen carbonate. The physiological role of the enzyme is to generate ATP.
