Enzyme-catalysed reactions can involve significant quantum tunnelling and show kinetic isotope effects with complex temperature dependences. In this Perspective, reaction dynamics and enzyme catalysis are linked to transition-state-theory frameworks. It is shown that a multi-state model using standard transition-state theory can account for complex experimental data without invoking a role for enzyme dynamics.
