Fluorescence Determination of Tryptophan Side-Chain Accessibility and Dynamics in Triple-Helical Collagen-Like Peptides

We report tryptophan fluorescence measurements of emission intensity, iodide quenching, and anisotropy that describe the environment and dynamics at X and Y sites in stable collagen-like peptides of sequence (Gly-X-Y)(n). About 90% of tryptophans at both sites have similar solvent exposed fluorescen...
