Peptides are an important class of biomolecules that perform many physiological functions and which occupy a significant and increasing share of the pharmaceutical market. Methods to determine the solid-state structures of peptides in different environments are important to help understand their biological functions and to aid the development of drug formulations. Here, a new magic-angle spinning (MAS) solid-state nuclear magnetic resonance (SSNMR) approach is described for the structural...

A large geometric distortion in the first photointermediate of rhodopsin, determined by double-quantum solid-state NMR
A large geometric distortion in the first photointermediate of rhodopsin, determined by double-quantum solid-state NMR
Abstract Double-quantum magic-angle-spinning NMR experiments were performed on 11,12-13C2-retinylidene-rhodopsin under illumination at low temperature, in order to characterize torsional angle changes at the C11-C12 photoisomerization site. The sample was illuminated in the NMR rotor at low temperature (~120 K) in order to trap the primary photointermediate, bathorhodopsin. The NMR data are consistent with a strong torsional twist of the HCCH moiety at the...
