Inductive Effects on the Energetics of Prolyl Peptide Bond Isomerization: Implications for Collagen Folding and Stability.

Journal of the American Chemical Society

Eberhardt ES, Panisik N, Raines RT.
PMID: 21451735
J Am Chem Soc. 1996;118(49):12261-12266. doi: 10.1021/ja9623119.

The hydroxylation of proline residues in collagen enhances the stability of the collagen triple helix. Previous X-ray diffraction analyses had demonstrated that the presence of an electron-withdrawing substituent on the pyrrolidine ring of proline residues has significant structural consequences...

Biochemistry. 1998 Feb 10;37(6):1686-96. doi: 10.1021/bi971937o.

The introduction into peptide chains of alpha-aminoisobutyric acid (Aib) has proven to stabilize the helical structure in short peptides by restricting the available range of polypeptide backbone conformations. In order to evaluate the potential stabilizing effect of Aib at...
