ENZYME entry: EC 4.2.1.104

Accepted Name
Cyanase.
Alternative Name(s)
Cyanate aminohydrolase.
Cyanate C-N-lyase.
Cyanate hydratase.
Cyanate hydrolase.
Cyanate lyase.
Reaction catalysed
Cyanate + HCO(3)(-) + 2 H(+) <=> NH(3) + 2 CO(2)
Comment(s)
  • 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.
