Patterns and conformations of commonly occurring supersecondary structures (basic motifs) in protein data bank

Short peptides connectingα-helices andβ-strands have been analyzed in 240 proteins refined at resolutions of 0.25 nm or better. Connecting peptides of lengths between one and five residues have been classified as...
