IUBMB Comments
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 , and hence the enzyme is classified as a hydrolase.
