Sysname
carbamate hydro-lyase
Reaction(IUBMB)
cyanate + hydrogencarbonate + 2 H+ = NH3 + 2 CO2 (overall reaction) [RN:
R10079 ];
(1a) cyanate + hydrogencarbonate + H+ = carbamate + CO2 [RN:
R03546 ];
(1b) carbamate + H+ = NH3 + CO2 (spontaneous) [RN:
R07316 ]
Reaction(KEGG)
Substrate
Product
Comment
This enzyme, which is found in bacteria and plants, is used to decompose cyanate, which can be used as the sole source of nitrogen [6,7]. Reaction (1a) can be considered an equivalent of 'cyanate + H2O = carbamate', where the water molecule is provided by the dehydration of bicarbonate to carbon dioxide [2], and hence the enzyme is classified as a hydrolase.
