Surface-enhanced resonance Raman scattering (SERRS) spectra of phytochrome at 77 K are reported. The spectra reveal significant differences between Pr and Pfr forms of phytochrome. SERRS spectra of C-phycocyanin Z,Z,Z- and Z,Z,E-chromopeptide isomers at 77 K are also reported. The phycocyanin chromopeptide studies are used to provide a basis for interpreting the phytochrome SERRS spectra. The spectra indicate that photoisomerization of chromophores from C-phycocyanin chromopeptides (from a Z,Z,Z to a Z,Z,E configuration) is detectable with SERRS.
