Resumen:
Post-translational modifications (PTMs) on proteins significantly enlarge the physicochemical diversity present in biological macromolecules, altering function, localization, and interactions. Despite their critical role in regulating cellular processes, theoretical methods are not yet fully capable of coping with this diversity. These limitations are particularly more marked for coarse-grained (CG) models, in which comprehensive and self-consistent parametrizations are less frequent. Here we present a set of topologies and interaction parameters for the most common PTMs, fully compatible with the SIRAH force field. The PTMs introduced here reach the same level of structural description of the existing SIRAH force field, expanding the chemical spectrum with promising applications in dynamical protein?protein interactions in large and complex cellular environments.
