Transformation of the mechanism of triple-helix peptide folding in the absence of a C-terminal nucleation domain and its implications for mutations in collagen disorders.

Abstract excerpt

Folding abnormalities of the triple helix have been demonstrated in collagen diseases such as osteogenesis imperfecta in which the mutation leads to the substitution of a single Gly in the (Gly-X-Y)n sequence pattern by a larger residue. Model peptides can be used to clarify the details of normal collagen folding and the consequences of the interruption of that folding by a Gly substitution. NMR and CD studies...
