ENZYME entry: EC 4.3.1.13

Accepted Name
Carbamoyl-serine ammonia-lyase.
Alternative Name(s)
O-carbamoyl-L-serine deaminase.
Reaction catalysed
O-carbamoyl-L-serine + H(2)O <=> pyruvate + 2 NH(3) + CO(2)
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • The enzyme cleaves a carbon-oxygen bond, releasing CO(2), ammonia, and an unstable enamine product that tautomerizes to an imine form, which undergoes a hydrolytic deamination to form pyruvate and a second ammonia molecule.
  • The latter reaction, which can occur spontaneously, can also be catalyzed by EC 3.5.99.10.
