Figure 7
Spectroscopic data corresponding to the proteins represented in Fig. 6[link]. (a, d) Comparison of reduced and oxidized proteins. (b, e) Photoreduction monitored by UV-vis absorption. (c) Buildup of a peroxo intermediate demonstrated by Raman spectroscopy using isotopically labelled hydrogen peroxide. The isotopic effect is indicated by purple arrows. (f) Comparison of the dark and meta-II intermediate states of bovine rhodopsin. (g) Comparison of absorption spectra in solution and crystalline states. (h) Photobleaching of a fluorescent protein monitored by fluorescence spectroscopy. (i) The presence of a disulfide bond probed by Raman spectroscopy. The position of the disulfide-bridge stretching mode is indicated by an arrow.
