HighlightsKinetic studies on isotopically substituted enzymes are a useful tool to evaluate the impact of protein motions in the chemical step.Recent experimental and theoretical works on enzyme kinetic isotope effects are reviewed.The observed enzymatic kinetic isotope effects can be interpreted using Transition State Theory.Protein motions of different time-scales can participate in the reaction coordinate although the use of the term ‘dynamical effects’ can be misleading.The role of protein motions in the chemical step of enzyme-catalyzed reactions is the subject of an open debate in the scientific literature. The systematic use of isotopically substituted enzymes has been revealed as a useful tool to quantify the role of these motions. According to the Born–Oppenheimer approximation, changing the mass of the protein does not change the forces acting on the system but alters the frequencies of the protein motions, which in turn can affect the rate constant. Experimental and theoretical studies carried out in this field are presented in this article and discussed in the framework of Transition State Theory.
