The application of kinetic isotope effects and molecular modeling to characterize three enzyme-catalyzed reactions is presented; the mechanism of the chloroacid dehalogenase catalyzed reaction is approached using chlorine kinetic isotope effects and solvent kinetic isotope effects. The pre-steady-state phase of the reaction catalyzed by methylmalonyl-CoA mutase is approached by different QM/MM schemes and the results are validated by comparison with the experimental value of the deuterium… CONTINUE READING
