From the most recent Brookhaven Protein Co-ordinate Databank, 229 sequence-identical pentapeptide pairs, each found in two unrelated protein structures, were collected; 9115 such pairs differing in only one residue were also gathered. For both samples the main-chain fold was conserved about 20% of the time, despite the different atomic environments presented by the unrelated protein architectures. An analysis of the substituted residues as well as the composition of the sequence-similar pentapeptides allowed several suggestions regarding protein folding mechanisms. An examination of the most frequently observed residue substitutions and their correlation with structural changes in the oligopeptide pairs yields a possible guide for site-directed mutagenesis experiments, especially when no tertiary structural information is at hand.
