Computed Atlas of Surface Topography of proteins (CASTp) locates and measures concave surface regions on 3D protein structures. This tool can be used to study surface features, binding sites, and functional regions of proteins.
Tools developed to aid in the identification of mass spectrum that allow the calculation of mass values with isotopic distributions based on molecular formulas, peptides/proteins, DNA/RNA, carbohydrate sequences or combinations thereof. A viewer for visualizing results is also available.
The MEME Suite web server is a unified portal for discovery and analysis of sequence motifs (e.g. DNA binding sites, protein interaction domains). Motifs with/without gaps may be discovered, searched for in DNA and protein databases, compared to other motifs and analyzed for putative function by association with gene ontology terms.
MEME is a tool designed for discovering and searching for DNA motifs such as transcription factor binding sites (TFBS) or protein domains.
Normal Mode Analysis, Deformation, and Refinement (NOMAD-Ref) provides tools for calculating functionally relevant movements in biological macromolecules. This resource provides tools for investigating different conformations of large protein structures, for modeling receptor/ligand docking complexes, and for calculating the associated molecular motions.
PBEQ-Solver is a wb based graphical user interface to read biomolecular structures, solve the Poisson-Boltzmann equations and interactively display the eletrostatic potential.
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.
PDB_Hydro provides tools for mutating and solvating structures of biological macromolecules like proteins or DNA. It identifies strongly and poorly solvated exposed surfaces of structures in an effort to help identify potential interaction zones.
