英文摘要	Phycobilisomes (PBSs) are the largest light-harvesting complexes in cyanobacteria and red algae. To understand the energy transfer dynamics in PBSs, the cyanobacterium Thermosynechococcus vulcanus NIES 2134 (T 2134), with a phycocyanin (PC) trimer PC612 linking the rod and core, was selected. The energy transfer dynamics were studied via time-resolved fluorescence spectroscopy with sub-picosecond resolution. The energy transfer pathways and transfer rates were uncovered by deconvolution of the fluorescence decay curve. A fast time-component of 10 ps from PC612 trimer to the core and a slow time-component of 80 ps from rods to the core were recognized in the energy transfer. The faster energy transfer rate of 10 ps enables PC612 trimer to modulate the energy transfer dynamics between rods and core. The findings help us understand the structure-induced energy transfer mechanisms in PBSs.
