Analyser and viewer of protein inter-residue contacts

This service is made in order to achieve more efficient insight into the nature of hydrophobic or hydrophilic forces in proteins. It enables to visualize details and specificity in contacts between amino acid residues in proteins. In addition, it is possible to visualize contributions of inter-residue contacts depending on selected physical and chemical properties of amino acid residues (current version is based on the hydrophobicity scale intoroduced by J. Kyte and R. F. Doolittle, J. Mol. Biol., vol. 157, p. 105-132, 1982). Choosing one amino acid residue, distances between its side chain and side chains of all amino acid residues within the sphere of chosen radius can be visualized. Current version of database included in the server contains only 100 proteins crucial for performing research on modeling of protein folding rates and some antimicrobial polypetides, but it will be enlarged by new sequences. Visualization is available in png, povray, and vrml format, and the PDB format output is also available.
