In analogy to the cystineknots present in natural collagens, a simplified disulfide cross-link was used to analyse the conformational effects of a C-terminal artificialcystineknot on the folding of collagenous peptides consisting of solely (Pro-Hyp-Gly) repeating units. Assembly of the alpha chains into a heterotrimer by previously applied regioselective disulfide-bridging strategies failed because
