Disallowed Ramachandran conformations of amino acid residues in protein structures.
An analysis of the nature and distribution of disallowed Ramachandran conformations of amino acid residues observed in high resolution protein crystal structures has been carried out. A data set consisting of 110 high resolution, non-homologous, protein crystal structures from the Brookhaven Protein Data Bank was examined. The data set consisted of a total of 18,708 non-Gly residues, which were...
متن کاملThe CHA2DS2-VASc score identifies those patients with atrial fibrillation and a CHADS2 score of 1 who are unlikely to benefit from oral anticoagulant therapy.
AIMS The CHA(2)DS(2)-VASc score is a modification of the CHADS(2) score that aims to improve stroke risk prediction in patients with atrial fibrillation (AF) by adding three risk factors: age 65-74, female sex, and history of vascular disease. Whereas previous evaluations of the CHA(2)DS(2)-VASc score included all AF patients, the aim of this analysis was to evaluate its discriminative ability ...
متن کاملDictionary of Protein Stereochemistry
A computer-readable dictionary for protein structure refinement is presented. The dictionary is based on the set of interatomic bonds and bond angles previously derived from small-molecule structures by Engh & Huber [Acta Cryst. (1991), A47, 392-400]. The internal inconsistency of the set is discussed. Some preliminary results derived from several protein structures refined at atomic resolution...
متن کامل3d Perception of Maximum Density Zone on Ramachandran Plots for Zika Virus Protein Structures
The Ramachandran plot is among the most central concepts in structural biology which uses torsion angles to describe polypeptide and protein conformation. To help visualize the features of high-fidelity Ramachandran plots, it is helpful to look beyond the common two-dimensional psi-phi-plot, which for a large dataset does not serve very well to convey the true nature of the distribution. In par...
متن کاملThree-helix-bundle protein in a Ramachandran model.
We study the thermodynamic behavior of a model protein with 54 amino acids that forms a three-helix bundle in its native state. The model contains three types of amino acids and five to six atoms per amino acid and has the Ramachandran torsional angles phi(i), psi(i) as its degrees of freedom. The force field is based on hydrogen bonds and effective hydrophobicity forces. For a suitable choice ...
