Basic aim of the server is to analyze the protein interface in a protein complex. Users can provide a valid PDB file name ( e.g 1BBB, only four letter PDB code). Server uploads the PDB file and calculates the following properties.

1) Residues present at the protein interface.
2) Polar area and apolar area of amino acid residues.
3) Number of surface and buried atoms.
4) Total area of the protein, in its monomeric form and within a protein complex.
