Background: Phycobiliproteins are located in phycobilisomes, which are huge pigmentprotein
complexes that function as light harvesting antennas for photosynthesis in
cyanobacteria, red algae and other uncommon species.
Methods: The research progress of structures of the pigmented-covalently-binding
phycobiliproteins were reviewed, including PhycoCyanin (PC), AlloPhycoCyanin
(APC), PhycoErythroCyanin/PhycoErythrin (PEC/PE) and linkers. In addition, the
progress of their combinational biosynthesis was also visited.
Results: We summarized advances in the development of phycobiliproteins-Sensitized
Solar Cells (Dye Sensitized Solar Cells, DSSC) with high photoelectric transfer efficiency and low cost. Meantime, the
efficiencies were compared on phycobilisome-based and bacteriochlorophyll/ chlorophyll-Sensitized Solar Cells. It was also
discussed that directional molecular design of phycobiliproteins, for artificial high-level structure.
Conclusion: To accomplish higher level assembling of in vitro synthesis of phycobiliproteins requires technology for multichromophore
attachment to apo-phycobiliproteins, and an understanding of linkers’ function in high-level phycobilisome
