Enzyme Information
| 6.3.4.16 |
Carbamoyl-phosphate synthase (ammonia).
based on mapping to UniProt P31327
2 ATP + NH(3) + HCO(3)(-) = 2 ADP + phosphate + carbamoyl phosphate.
-!- The enzyme catalyzes the first committed step in the urea cycle. -!- The reaction proceeds via three separate chemical reactions: phosphorylation of hydrogencarbonate to carboxyphosphate; a nucleophilic attack of ammonia on carboxyphosphate yielding carbamate; and the phosphorylation of carbamate forming carbamoyl phosphate. -!- Two moles of ATP are utilized for the synthesis of one molecule of carbamyl phosphate, making the reaction essentially irreversible. -!- The enzyme requires the allosteric activator N-acetyl-L-glutamate. -!- Cf. EC 6.3.5.5. -!- Formerly EC 2.7.2.5.
