Abstract

This chapter aims to present some basic multiscale approaches available for enzyme simulations, and to point out practical details and pitfalls that are not often discussed in the literature, but can greatly influence the outcome of any in silico enzyme study. We cover principle methodological steps of multiscale studies of general enzyme reactions. This includes choice of starting structures, boundary conditions, potential energy surfaces, reaction coordinates, simulation methods, as well as the choice of method for the treatment of nuclear quantum effects. Together, these and additional steps are crucial for the success of enzyme-modeling projects and should be considered prior to embarking on multiscale modeling.

How strong is the evidence?

Evidence Hub reads this as a review, done in computer models (in silico), not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
