Selective interface detection: mapping binding site contacts in membrane proteins by NMR spectroscopy.

Intermolecular contact surfaces are important regions where specific interactions mediate biological function. We introduce a new magic angle spinning solid state NMR technique, dubbed "selective interface detection spectroscopy" (SIDY). In this technique, 13C-attached protons (1Hlig) are dephased by 1H-13C REDOR. A spin diffusion period is then used to… CONTINUE READING
