    31. reconstitution of the zinc active site of human CA II PMID: 23030313
    32. data suggest that the Ile substitution at position 143 reduced the catalytic efficiency, likely due to steric crowding resulting in destabilization of the transition state for conversion of CO(2) into bicarbonate and a decreased product dissociation rate. PMID: 23098192

    37. The apparent values of the pK(a) of the zinc-bound water and the proton shuttle residue suggest that different active-site conformations influence the two stages of catalysis, the proton transfer stage and the interconversion of CO(2) and bicarbonate. PMID: 22001224
    38. Detailed analysis and comparison to the previously determined structure of CAII at pH 10.0 show important differences in protonation of key catalytic residues in the active site as well as a rearrangement of the hydrogen-bonded water network. PMID: 21988105

    42. The H(+) shuttle in CAII not only facilitates CAII catalytic activity but also can enhance activity of acid-/base-transporting proteins such as MCT1/4 in a direct, noncatalytic manner, possibly by acting as an "H(+)-collecting antenna." PMID: 21282642
    43. The side chain of Tyr7 in CA II extends into the active-site cavity about 7 A from the catalytic zinc atom. Replacement of Tyr7 with eight other amino acids had no effect on the interconversion of bicarbonate and CO2. PMID: 21145876
