Structure Validation and Quality

  • MolProbity
    Structure validation on client-uploaded or PDB ID-specified files, using all-atom contact analysis tools and updated geometrical criteria for phi/psi, sidechain rotamer, and Cbeta deviation
  • NQ-Flipper
    NQ-Flipper recognizes unfavorable rotamers of Asn and Gln residues in protein structures obtained from X-ray crystallography, NMR or modelling studies.
  • Procheck
    A program that checks the stereochemical quality of a protein structure
  • Prosa-web
    Quality scores of a protein are displayed in the context of all known protein structures and problematic parts of a structure are shown and highlighted in a 3D molecule viewer.
  • Uppsala Electron Density Server
    Generated density maps
  • Verify3D Structure Evaluation Server
    A system for protein structure validation derived from the WHAT IF program
    A protein structure analysis program that may be used for mutant prediction, structure verification and molecular graphics
