　　In the present study,the electronic energy transfer pathways in trimeric and hexameric aggregation state of cyanobacteria C-phycocyanin(C-PC)were investigated in term of the F rster Theory.The present calculated results suggested that the energy transfer pathway in C-PC monomer is predominant from β-155 to β-84(1/K=13.4 ps),however,from α-84 of one monomer to β-84(1/K=0.3–0.4 ps)in a neighbor monomer in C-PC trimer.In C-PC hexamer,an additional energy flow was predicted to be from β-155(or α-84)in top trimer to adjacent β-155(or α-84)(1/K =0.5–2.7 ps)in bottom trimer.
