Joint neutron crystallographic and NMR solution studies of Tyr residue ionization and hydrogen bonding: Implications for enzyme-mediated proton transfer

Human carbonic anhydrase II (HCA II) uses a Zn-bound OH(−)/H(2)O mechanism to catalyze the reversible hydration of CO(2). This catalysis also involves a separate proton transfer step, mediated by an ordered solvent network coordinated by hydrophilic residues. One of these residues, Tyr7, was previou...
