Any Interaction interface residues detection tool which can detect out the residues involved and their role and functional quantification?
The tool PISA is designed to do this

However, you should always use experimental methods to verify what computations indicate.
Thank You Christina. It is really helpful for me.
@ Ahmed. Thanks for your link but I was looking for a 3D tool that was suggested by Christina.
FoldX will be an another option.
Module to use:
FoldX says: "The program just mutates every residue on the interface of the selected molecules to Ala and produces the ΔΔG of the mutation."
In addition to Priybrata Panigrahi, I would advice you to consider computationnal alanine scanning.
An alternative of FoldX based on molecular dynamics simulation and MM/PBSA estimation of the binding free energy using AmberTools. ( http://ambermd.org/ ; http://ambermd.org/tutorials/advanced/tutorial3/py_script/section3.htm )
It has been succesfully applied to tubulin to identify identify the amino acids responsible for tubulin–tubulin binding and thus to design anti-mitotic peptides.
