ENZYME entry: EC 4.2.1.104

PURL: https://purl.expasy.org/enzyme/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 + hydrogencarbonate + 3 H(+) = NH4(+) + 2 CO2
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 + H2O', 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.
