MolProbity is a structure validation web service for diagnosing problems in 3D models of proteins, nucleic acids or complexes. It adds and optimizes H atoms (correcting 180° flipped Asn/Gln/His sidechains), and then calculates global and local validation for all-atom contacts (steric clashes, H-bonds & vdW), covalent geometry, and conformation (Ramachandran & rotamers for protein, ribose puckers & suite conformers for RNA). Results are displayed online as 3D graphics and sortable charts.
MoViES (Molecular Vibrations Evaluation Server) allows the computation of the vibrational and thermal fluctuations dynamics for the chemical bonds of biomolecules. The server takes as input a structure file in PDB format and returns results by email. Analysis of vibrational motions and thermal fluctuational dynamics can give insights into the functional properties of both proteins and nucleic acids.
Server that allows users to convert PDB files into PQR files by adding missing atoms, optimizing hydrogen bonding and assigning atomic charge and radius parameters. The resulting PQR file can be used for electrostatic calculations which can give insight into the influence of electrostatics on biomolecular structures.
PFP (Patch Finder Plus) is a tool for extracting and displaying positive electrostatic patches on protein surfaces which can be indicative of nucleic acid binding interfaces.
Protein Interactions Calculator (PIC) is a server which recognizes various kinds of interactions; such as disulphide bonds, hydrophobic interactions, hydrogen bonds, aromatic interactions, and ionic interactions within a protein or between proteins in a complex.
Readout is a server for the calculation of direct and indirect readout energy Z-scores which estimate the degree of sequence specificity of the protein-DNA complex. Readout can be useful for checking the quality of protein-DNA interactions in three dimensional (3D) structures.
SPACE (Structure Prediction and Analysis based on Complementarity with Environment) is a suite of tools for predicting and analyzing structures of biomolecules and their complexes.
