NQ-Flipper 2.7 – Validate Asparagine and Glutamine Side-chain Amide Rotamers in Protein Structures

NQ-Flipper 2.7

:: DESCRIPTION

NQ-Flipper recognizes unfavorable rotamers of Asn and Gln residues in protein structures. This service is applicable to structures obtained from X-ray crystallography, NMR or modeling studies. The method is based on knowledge-based potentials of mean force compiled from a database of known protein structures determined by X-ray crystallography. The potentials are then refined by several cycles of rotamer correction and recompilation of potentials. The refined potentials are used here to validate or correct asparagine and glutamine amide rotamers.

QuickPDB 20021101 – Java Applet for quickly viewing PROTEIN PDB Structure

QuickPDB 20021101

:: DESCRIPTION

QuickPDB permits you to find and quickly review a macromolecular structure looking at interactions between sequence and structure. Typically, once you have located structure(s) of interest you would download then for further analysis using local programs. QuickPDB is also available from the View Structure section of the Structure Explorer page for any entry in the Protein Data Bank .

Voronoia 1.0 – Analyse Packing of Protein Structures

Voronoia 1.0

:: DESCRIPTION

Voronoia is a program suite to analyse and visualize the atomic packing of protein structures. It is based on the Voronoi Cell method and can be used to estimate the quality of a protein structure, e.g. by comparing the packing density of buried atoms to a reference data set or by highlighting protein regions with large packing defects. Voronoia is also targeted to detect locations of putative internal water or binding sites for ligands. Accordingly, Voronoia is beneficial for a broad range of protein structure approaches. It is applicable as a standalone version coming with a user friendly GUI or, alternatively, as a Pymol Plugin. Finally, Voronoia is also available as an easy to use webtool to process user defined PDB-files or to asses precalculated packing files from DOPP, the regularly updated Dictionary of Packing in Proteins.
