Controlling electron transfer between the two cofactor chains of photosystem I by the redox state of one of their components.

Biophysical journal - 24 Mar 2015

Santabarbara Stefano, Bullock Bradford, Rappaport Fabrice, Redding Kevin E

Abstract excerpt

Two functional electron transfer (ET) chains, related by a pseudo-C2 symmetry, are present in the reaction center of photosystem I (PSI). Due to slight differences in the environment around the cofactors of the two branches, there are differences in both the kinetics of ET and the proportion of ET that occurs on the two branches. The strongest evidence that this is indeed the case relied on the observation that...
