Scoring Docked Protein Complexes with Hydrogen Bonds
Finding the structure of proteins and protein-protein complexes is an important problem in the field of computational biology. Determining protein structures can be done successfully with various experimental methods like x-ray crystallography, but determining protein-protein structures experimentally is more difficult. Instead, these structures are frequently predicted computationally. One app...
متن کاملStrong and weak hydrogen bonds in the protein-ligand interface.
The characteristics of N--H...O, O--H...O, and C--H...O hydrogen bonds and other weak intermolecular interactions are analyzed in a large and diverse group of 251 protein-ligand complexes using a new computer program that was developed in-house for this purpose. The interactions examined in the present study are those which occur in the active sites, defined here as a sphere of 10 A radius arou...
متن کاملThe Nature of Halogen Bonds in [N∙∙∙X∙∙∙N]+ Complexes: A Theoretical Study
The effects of substituents on the symmetry and the nature of halogen bonds in [N∙∙∙X∙∙∙N]+-type systems are presented for the YC5H4N∙∙∙X∙∙∙NC5H5 (Y = NO2, CN, H, CH3, OCH3, OH, NH2, X = Cl, Br, I) complexes. Some structural parameters, energy data and electronic properties were explored with...
متن کاملHydrogen placement in protein-ligand complexes under consideration of tautomerism
Protein-ligand complexes are often consulted for the understanding of binding modes and mechanisms of action as well as the development of novel drugs. Unfortunately the resolution of most x-ray structures is too low to resolve hydrogen atoms. However, hydrogen positions play a major role in the analysis of important interaction types as hydrogen bonding or metal interactions. Therefore, it is ...
متن کاملH2XP:OH2 Complexes: Hydrogen vs. Pnicogen Bonds
A search of the Cambridge Structural Database (CSD) was carried out for phosphine-water and arsine-water complexes in which water is either the proton donor in hydrogen-bonded complexes, or the electron-pair donor in pnicogen-bonded complexes. The range of experimental P-O distances in the phosphine complexes is consistent with the results of ab initio MP2/aug’-cc-pVTZ calculations carried out ...
