Protein chemical shifts are routinely used to augment molecular mechanics force fields in protein structure simulations, with weights of the chemical shift restraints determined empirically. These weights, however, might not be an optimal descriptor of a given protein structure and predictive model, and a bias is introduced which might result in incorrect(More)
We present ProCS15: a program that computes the isotropic chemical shielding values of backbone and Cβ atoms given a protein structure in less than a second. ProCS15 is based on around 2.35 million OPBE/6-31G(d,p)//PM6 calculations on tripeptides and small structural models of hydrogen-bonding. The ProCS15-predicted chemical shielding values are compared to(More)
Additional supplementary material, including the structures used in the chemical shift prediction, can be found on Table S1. UniProt codes, names, PDB IDs and resolution of the X-ray structures, residues included in the models, and the BMRB codes of the chemical shift data of the 17 proteins used in this study.
