Effects of freezing out protein vibrational modes on electron transfer kinetics in bacterial reaction centers.

T Kakitani1, N Mataga.   

Abstract

We propose a model that some vibrational modes of the protein in bacterial photosynthetic reaction centers may be frozen at low temperatures. The freezing of the protein-environmental motion can affect the electron transfer rate through changes in the reorganization energy and the free energy gap. We offer a qualitative explanation of the different kinetics of the ET processes in reaction centers which are cooled in the dark and cooled under illumination.
