Predicting peptide binding site of a protein

Question

[biobiu]

Hello, I'm aiming to predict, for a protein of interest, its likelihood to bind a peptide (non-specific peptide, lets assume an optimal peptide exists). Any ideas how to do that? I was thinking to use a tool like SPRINT-STR but it seems to be offline.

The perfect tool will allow me to evaluate for a list of proteins which has highest probability to be targeted by peptides.

Thanks!
