| Time-Resolved Polarized Fluorescence of C-Phycocyanin and Its Subunits from Mastigocladus laminosus  | | | | Abstract
| The influence o f aggregation and temperature on the excited state kinetics o f C -phycocyanin from Mastiqocladus laminosus has been studied. Polarized fluorescence decay curves have been recorded using a synchronously pum ped dye laser in conjunction with a synchroscan streak camera. The experimental data for all sam ples can be fit satisfactorily assum ing a biexponential decay law. Fluorescence depolarization tim es have been interpreted in terms o f energy transfer among the different chromophores. The influence o f temperature is only m oderate on the intra molecular relaxation, but pronounced on the rates o f energy transfer. Both are dependent on the size o f the aggregate. The biexponential decay o f the a-subunit containing only one Chromo phore, indicates the presence o f different subsets o f chrom ophores in these sam ples. The results are discussed in terms o f variations o f the chrom ophore arrangem ents upon temperature induced changes in the protein conformation. | | | |
