IUBMB Comments
The enzyme catalyses the reversible hydration of gaseous CO2 to carbonic acid, which dissociates to give hydrogencarbonate above neutral pH. It is widespread and found in archaea, bacteria, and eukaryotes. Three distinct classes exist, and appear to have evolved independently. Contains zinc.
