Abstract

A structure consisting of the polyproline-II or collagen-like helix immediately succeeded by a β-turn is seen in several synthetic peptides and has been suggested to be the conformational requirement for proline hydroxylation in nascent procollagen. Using a simple algorithm for detecting secondary structures, we have analysed crystal structure data on 40 globular proteins and have found eight examples of the collagen-helix + β-turn supersecondary structure in 15 proteins that contain the collagen-like helical segments.
