The role of promoting vibrations in enzymic reactions involving hydrogen tunnelling is contentious. Whilemodels incorporating such promoting vibrations have successfully reproduced and explained experimental observations, it has also been argued that such vibrations are not part of the catalytic effect. In this study,we have employed combined quantum mechanical/molecular mechanical methods ...
