ID   4.2.1.1
DE   carbonic anhydrase.
AN   carbonate dehydratase.
AN   carbonate hydro-lyase.
AN   carbonic dehydratase.
CA   H(+) + hydrogencarbonate = CO2 + H2O.
CC   -!- The enzyme catalyzes the reversible hydration of dissolved CO2 to
CC       carbonic acid, which dissociates to give hydrogencarbonate above
CC       neutral pH.
CC   -!- It is widespread and found in archaea, bacteria, and eukaryotes.
CC   -!- Three distinct classes exist, and appear to have evolved
CC       independently.
