CCL: protein-small molecules reactions



dear all,

i'm studying the reaction between a protein and a small molecule. from experiments we know it forms covalent adducts to four residues, which have been clearly identified.

my question is: how can i predict, from the structures of both the protein and the molecule, which are the residues most likely to react?

i was planning to get a solvent accessibility map of the protein and then "react" the molecule to those residues (we know it's an sn2 reaction), but i can't figure out what approach to use to model those reactions using the **whole protein**.

any comments will be very much appreciated!

cheers,
g.
