MyPMFs: a simple tool for creating statistical potentials to assess protein structural models.

MyPMFs: a simple tool for creating statistical potentials to assess protein structural models. Biochimie. 2018 May 29;: Authors: Postic G, Hamelryck T, Chomilier J, Stratmann D Abstract Evaluating the model quality of protein structures that evolve in environments with particular physicochemical properties requires scoring functions that are adapted to their specific residue compositions and/or structural characteristics. Thus, computational methods developed for structures from the cytosol cannot work properly on membrane or secreted proteins. Here, we present MyPMFs, an easy-to-use tool that allows users to train statistical potentials of mean force (PMFs) on the protein structures of their choice, with all parameters being adjustable. We demonstrate its use by creating an accurate statistical potential for transmembrane protein domains. We also show its usefulness to study the influence of the physical environment on residue interactions within protein structures.
