Amide-Amide and Amide-Water Hydrogen Bonds: Implications for Protein Folding and Stability [PDF]
Journal of the American Chemical Society, 1994 Amide-amide hydrogen bonds have been implicated in directing protein folding and enhancing protein stability. Inversion transfer (13)C NMR spectroscopy and IR spectroscopy were used to compare the ability of various amide solvents and of water to alter the rate of the cis-trans isomerization of the prolyl peptide bond of Ac-Gly-[β,δ-(13)C]Pro-OMe and ...
