Abstract

The vlue of vibrational spectroscopy in the study of biopolymers has been greatly enhanced by adding the new dimension of optical activity [1]. The Raman optical activity (ROA) approach, which measures a small difference in the intensity of Raman scattering in right and left circularly polarized incident light, has been transformed by recent technical advances into a powerful new biochemical spectroscopy [2]. Since protein ROA spectra contains bands from loops and turns in addition to secondary structure, they contain information about the tertiary backbone fold and hence the three-dimensional solution structure. This, plus a special sensitivity to conformational mobility and the short timescale of the Raman scattering process, makes ROA ideal for studying dynamic aspects of structure in both non-native [3, 4] and native [5] states.
