prediction of protein-protein contact sites

[Carsten Hohoff]

Dear Netters, 

I have evidence that two proteins interact with each other. I know the
tertiary structure of one and can model the 3D structure of the other on the basis of 
related proteins - is there any program that allows for the prediction of
the sites of protein-protein interaction? 

Thanx in advance
