Enzyme Information
| 4.2.1.104 |
Cyanase.
based on mapping to UniProt P00816
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.
