PFP or PFplus / PatchFinderPlus is a web-based tool for extracting and displaying continuous electrostatic positive patches on protein surfaces. The input required for PFplus is either a four letter PDB code or a protein coordinate file in PDB format, provided by the user. PFplus computes the continuum electrostatics potential and extracts the largest positive patch for each protein chain in the PDB file.
Given a protein structure (PDB file), AFPredictor will predict potential ice-binding sites based on geometric analysis of the protein surface. It can be used to predict novel antifreeze proteins from 3D structure alone.
3D-SURFER is a web-based tool for real-time protein surface comparison and analysis. The server integrates a repertoire of methods to assist in high throughput screening and visualization of protein surface comparisons.
