Spectral analysis of allo phycocyanin i allo phycocyanin ii allo phycocyanin iii and allo phycocyanin b from nostoc sp phycobilisomes

, : Spectral analysis of allo phycocyanin i allo phycocyanin ii allo phycocyanin iii and allo phycocyanin b from nostoc sp phycobilisomes. Biochimica et Biophysica Acta 592(2): 267-276

Low temperature ( C) and room temperature ( C) absorption spectra of a family of allophycocyanin spectral forms isolated from Nostock sp. phycobilisomes as well as of the phycobilisomes themselves were analyzed by Gaussian curve-fitting. Allophycocyanin I and B share long wavelength components at 668 and 679 nm, bands that are absent from allophycocyanin II and III. These long wavelength absorption components are apparently responsible for the 20 nm difference between the 680 nm fluorescence emission maximum of allophycocyanin I and B and the 660 nm maximum of II and III. This indicates that allophycocyanin I and B are the final acceptors of excitation energy in the phycobilisome and the excitation energy transfer bridge linking the phycobilisome with the chlorophyll-containing thylakoid membranes. These Gaussian components are also found in resolved spectra of phycobilisomes, arguing against this family of allophycocyanin molecules being artifactual products of protein purification procedures.
