FunFam 46795: Cyanate hydratase

There are 1 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.

Cyanase. [EC: 4.2.1.104]
Cyanate + HCO(3)(-) + 2 H(+) = NH(3) + 2 CO(2).
  • This enzyme, which is found in bacteria and plants, is used to decompose cyanate, which can be used as the sole source of nitrogen.
  • The reaction can be considered as the reverse of 'carbamate = cyanate + H(2)O', where this is assisted by reaction with bicarbonate and carbon dioxide, and hence is classified in sub-subclass 4.2.1.
  • Bicarbonate functions as a recycling substrate.
  • Formerly EC 3.5.5.3 and EC 4.3.99.1.
