ENZYME entry: EC 3.5.1.84

Accepted Name
Biuret amidohydrolase.
Reaction catalysed
Biuret + H(2)O <=> urea-1-carboxylate + NH(3)
Comment(s)
  • Along with EC 3.5.2.15 and EC 3.5.1.54, this enzyme forms part of the cyanuric-acid metabolism pathway, which degrades s-triazide herbicides, such as atrazine (2-chloro-4-(ethylamino)-6- (isopropylamino)-1,3,5-triazine), in bacteria.
  • Urea-1-carboxylate rather than urea (as was thought previously) is the 2-nitrogen intermediate in cyanuric-acid metabolism in bacteria.
  • The product, urea-1-carboxylate, can spontaneously decarboxylate under acidic conditions to form urea but, under physiological conditions, it can be converted into CO(2) and ammonia by the action of EC 3.5.1.54.
