jsPISA is an interactive web tool for the calculation of macromolecular surfaces and interfaces, assessment of their properties and inference on probable macromolecular assemblies (complexes) from coordinate data, typically delivered by crystallographic X-ray experiment.
JET (Joint Evolutionary Trees) is a method designed to detect very different types of interactions of a protein with another protein, ligands, DNA, and RNA. It uses carefully designed sampling method, making sequence analysis more sensitive to the functional and structural importance of individual residues, and a clustering method parametrized on the target structure for the detection of patches on protein surfaces and their extension into predicted interaction sites.
