Short hydrogen bonds in proteins.
Short hydrogen bonds are present in many chemical and biological systems. It is well known that these short hydrogen bonds are found in the active site of enzymes and aid enzyme catalysis. This study aims to systematically characterize all short hydrogen bonds from a nonredundant dataset of protein structures. The study has revealed that short hydrogen bonds are commonly found in proteins and a...
متن کاملEnergetics of short hydrogen bonds in photoactive yellow protein.
Recent neutron diffraction studies of photoactive yellow protein (PYP) proposed that the H bond between protonated Glu46 and the chromophore [ionized p-coumaric acid (pCA)] was a low-barrier H bond (LBHB). Using the atomic coordinates of the high-resolution crystal structure, we analyzed the energetics of the short H bond by two independent methods: electrostatic pK(a) calculations and a quantu...
متن کاملTreatment of Hydrogen Bonds in Protein Simulations
The hydrogen bond plays an essential role in maintaining the secondary structures of protein, and an accurate description of hydrogen bond interaction is critical in protein folding simulation. Modern classical force fields treat hydrogen bonding as nonbond‐ ed interaction, which is dominated by electrostatic interaction. However, in the widely used nonpolarizable force fields, atomic charges a...
متن کاملScoring 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 کاملContribution of hydrogen bonds to protein stability.
Our goal was to gain a better understanding of the contribution of the burial of polar groups and their hydrogen bonds to the conformational stability of proteins. We measured the change in stability, Δ(ΔG), for a series of hydrogen bonding mutants in four proteins: villin headpiece subdomain (VHP) containing 36 residues, a surface protein from Borrelia burgdorferi (VlsE) containing 341 residue...
