Resonance Raman spectra of phycocyanin, allophycocyanin and phycobilisomes from blue-green alga Anacystis nidulans.

Resonance Raman spectra of native C-phycocyanin, allophycocyanin and whole, intact phycobilisomes from the blue-green alga Anacystis nidulans (Synechococcus 6301) are reported. A tentative assignment for the more prominent resonance Raman bands is suggested. The possibly sensitive regions for inter-chromophore interactions in the case of phycobilisomes are also discussed.
