Studies on Energy Transfer between Phycobiliproteins and Thylakoid Complex

The different concentrations C-phycocyanin (C-PC), Allophycocyanin (APC) or R-phycoerythrin(R-PE) solution can reconstitute with thylakoid to synthesize different donor-acceptor complexes. The energy transfer efficiencies of those complexes are studied, where C-PC, APC and R-PE are donor, the thylakoid are acceptor. The results show excitation energy can be transfered to thylakoid from C-PC or APC. However, the energy transfer process of R-PE to thylakoid membrane does not happen. The energy transfer process of the APC to thylakoid membrane shows the highest efficiency. Those results also indicate that the linkage between phycobiliproteins and thylakoid does not have specificity. It can be concluded that the energy transfer efficiencies not only strongly depend on the relative positions of donor and acceptor but also on spectral matching relation between phycobiliproteins and Chla molecules in thylakoid membrane.
