| 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.
