Excitation energy transfer in vitro between phycobiliproteins and thylakoid photosystem II of higher plants
- 35 Downloads
The excitation energy transfer from phycobiliproteins to thylakoid PSII of higher plants was investigated. When incubated with spinach thylakoids, phycobiliproteins isolated from red and blue-green algae transferred light energy absorbed to spinach PSII. The efficiency of energy transfer was dependent on the kind of phycobiliproteins used. If spinach thylakoids were replaced by the thylakoids ofBrassica chinensis, R-phycoerythin or C-phycocyanin did not transfer their excitation energy to PSII ofBrassica chinensis unless allophycocyanin was present.
