Structural studies of yeast iso-1 cytochrome c mutants by resonance Raman spectroscopy.


The Ser82 and Phe82 variants of yeast iso-1 cytochrome c were studied by resonance Raman spectroscopy. In both oxidation states, distinct spectral changes were observed for some of those bands in the low-frequency region, which sensitively respond to conformational perturbations of the protein environment of the heme. These bands can be assigned to modes… (More)
