Enzyme Information

4.2.1.1
Carbonic anhydrase.
based on mapping to UniProt P40881
H(2)CO(3) = CO(2) + H(2)O.
-!- The enzyme catalyzes the reversible hydration of gaseous CO(2) to carbonic acid, which spontaneously converts to hydrogencarbonate under neutral pH. -!- It is widespread and found in archaea, bacteria, and eukaryotes. -!- Three distinct classes exist, and appear to have evolved independently.
