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

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… (More)
