Compare the electrostatic potentials of proteins to classify them according to interaction properties

PIPSA (Protein Interaction Property Similarity Analysis) is a method to compare proteins according to their interaction properties. PIPSA may assist in function assignment, and the estimation of binding properties and enzyme kinetic parameters. The PIPSA webserver, webPIPSA, computes protein electrostatic potentials and corresponding similarity indices for a user-defined set of proteins. The standalone code, multipipsa, which includes a python wrapper, provides further options, including running PIPSA on multiple sites on a protein and performing a comparative analysis of the binding properties of user-defined groups of proteins.
