Energy transfer mechanism of PBS-thylakoid complexes

Conclusion In this work, we studied the energy transfer mechanism among PBS and two reaction centers (PS I and PS II) in PBS-thylakoid complexes by using steady-state spectra (77 K) and spectral deconvolution techniques. The experimental results indicated that the PBS-thylakoid complexes could perform the function of light state transition just like intact algae cell, and confirmed that PBSs were directly connected with PS I and PS II reaction centers separately. The energy transfer pathways from PBSs to two reaction centers are PBS-PS I and PBS-PS II.
