FunFam 19: Multifunctional urea amidolyase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Allophanate hydrolase. [EC: 3.5.1.54]
Urea-1-carboxylate + H(2)O = 2 CO(2) + 2 NH(3).
  • Along with EC 3.5.2.15 and EC 3.5.1.84, 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.
  • The Saccharomyces cerevisiae enzyme (but not that from green algae) also catalyzes the reaction of EC 6.3.4.6, thus bringing about the hydrolysis of urea to CO(2) and NH(3) in the presence of ATP and bicarbonate.
  • The enzyme from Pseudomonas sp. strain ADP has a narrow substrate specificity, being unable to use the structurally analogous compounds urea, hydroxyurea or methylcarbamate as substrate.

Urea carboxylase. [EC: 6.3.4.6]
ATP + urea + HCO(3)(-) = ADP + phosphate + urea-1-carboxylate.
  • The Saccharomyces cerevisiae enzyme (but not that from green algae) also catalyzes the reaction of EC 3.5.1.54, thus bringing about the hydrolysis of urea to CO(2) and NH(3).
  • The enzyme from the prokaryotic bacterium Oleomonas sagaranensis can also use acetamide and formamide as substrates.
  • Formerly EC 3.5.1.45.
