REVIEW : Recent advances in developing web-servers for predicting protein attributes (2009, background): “Its underpinning is based on the assumption that the number of protein folds is limited [228-231].”
Ensemble classifier for protein fold pattern recognition (2006, methodology): “In this paper, we shall resort to the taxonomic approach, whose underpinning is based on the assump-* tion that the number of protein folds is limited (Chou & Zhang, 1995; Dubchak et al., 1999; Finkelstein & Ptitsyn, 1987; Murzin et al., 1995).”
HorA web server to infer homology between proteins using sequence and structural similarity (2009, background): “Such ‘analogous’ similarity often comes from convergence to similar structures due to a limited number of energetically favorable ways to pack secondary structural elements (SSEs) ( 8 ,9).”
Discrimination between distant homologs and structural analogs: lessons from manually constructed, reliable data sets. (2008, methodology): “A.3. Intramolecule structure scores ( 1 ) DALI score (dali)”
SCOP: a structural classification of proteins database for the investigation of sequences and structures. (1995, background): “These regularities arise from the intrinsic physical and chemical properties of proteins (Chothia, 1984; Finkelstein & Ptitsyn, 1987) and provide the basis for the classification of protein folds (Levitt & Chothia, 1976; Richardson, 1981).”
