Computer-based protein modeling in structural biology Protein dynamics Exp. data analysis Protein design Virtual screening … Structure prediction is useful for molecular replacement, for docking in low-resolution maps, even by itself… http: //labriataphd. altervista. org/

Evaluating predictions of hard and very hard domains For small proteins there is very good chance of capturing topology, and even some chance of getting quite good models Very hard = no template at all Hard = template hard to find or structurally divergent Number of residues http: //labriataphd. altervista. org/
