Abstract
Raman spectroscopy may be profitably exploited to determine details of protein and nucleic acid structures and their mutual interactions in viruses and gene regulatory complexes. Present applications use data obtained from model nucleic acid crystals, fibers and solutions to reveal preferred backbone and nucleoside conformations for different morphological states of DNA and RNA in plant (TMV, BDMV) and bacterial viruses (P22, Pfl, Xf, Pf3, fd, Ifl, IKe). Interpretation of the results is enhanced by deconvolution methods which, in favorable cases, permit quantitative conclusions regarding macromolecular structures. Both equilibrium and dynamic Raman applications are described.
