The catalyzed rate of interconversion of CO2 and HCO3- at chemical equilibrium was the same for the acrolein-modified and the unmodified carbonic anhydrases, but the rate of release of 18O-labeled water from the active site had decreased by as much as 85% for the acrolein-modified enzyme.

Carbonic anhydrase VII (CA VII) appears to be the most highly conserved of the active mammalian carbonic anhydrases.
The magnitude of Kcat, its pH profile, 18O-exchange data for both wild-type and a H64A mutant, and inhibition by CuSO4 and acrolein suggest that the histidine at position 64 is functioning as a proton-transfer group and is responsible for one of the observed ionizations.
