ENZYME entry: EC 4.2.1.1

Accepted Name
carbonic anhydrase
Alternative Name(s)
carbonate dehydratase
carbonate hydro-lyase
carbonic dehydratase
Reaction catalysed
H(+) + hydrogencarbonate <=> CO2 + H2O
Comment(s)
  • The enzyme catalyzes the reversible hydration of dissolved 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.
