These are the ends of the loops, which are spatially close to each other but are situated apart in the polypeptide chain by 25-30 residues. They also correlate with the locations of highly conserved hydrophobic residues (referred to as topohydrophobic), in a structural alignment of the members of a protein family. This study analysed these positions in 111 representatives of different protein folds, and then carried out dynamic Monte Carlo simulations of the first steps of the folding process, aimed at predicting the origins of the assembling folds. The simulations demonstrated that there is an obvious trend for certain sets of residues, named Ômostly interacting residuesÕ, to be buried at the early stages of the folding process. Location of these residues at the loop ends and correlation with topohydrophobic positions are demonstrated, thereby giving a route to simulations of the protein folding process.
