摘要:
Raman spectroscopy has become a versatile tool in protein science and biotechnology. Recent advances in spectral assignments and vibrational theory, examples of use in structural biology and selected industrial applications are discussed. New insights into protein folding, assembly and aggregation were obtained by classical Raman spectroscopy. Raman spectroscopy has been used to characterize intrinsically unstructured proteins. The improved instrument sensitivity made it possible to use Raman difference spectroscopy to characterize enzyme-substrate interactions. Specifically, Raman crystallography has been instrumental in the delineation of protein-ligand interactions with a resolution surpassing that of x-ray diffraction. Numerous applications of Raman spectroscopy to protein analysis in biotechnology and food industry have been facilitated by the new generation of commercial Raman instruments.
