this is a tough challenge; in addition to the tutorials that Dan suggested
I would also suggest reading some of the literature on trying to predict
ligand binding to model structures for proteins. It's hard enough to
predict binding affinity with MD when the structure is known...
this might be a good start:
Modeling complexes of modeled proteins
Ivan Anishchenko, Petras J. Kundrotas, Ilya A. Vakser
DOI: 10.1002/prot.25183
and maybe this older one
Are predicted protein structures of any value for binding site prediction
and virtual ligand screening?
Jeffrey Skolnick, Hongyi Zhou, Mu Gao
