The electronic structure of Fe2+ in reaction centers from Rhodopseudomonas sphaeroides. I. Static magnetization measurements

TLDR
The Fe2+ and the spin on the quinone in reduced reaction centers were found to be coupled with an exchange interaction 0 less than /J/ less than 1 cm-1, implying that quin one is most likely not a ligand of Fe.

Oxidation‐Reduction Physical Chemistry of the Acceptor Quinone Complex in Bacterial Photosynthetic Reaction Centers: Evidence for a New Model of Herbicide Activity

TL;DR: It is suggested that ubiquinone and o-Phen compete for the B-site in a mutually exclusive fashion, and that their relative binding strengths are modulated by the redox and protonation state of QA.

Electron transfer in reaction centers of Rhodopseudomonas sphaeroides. I. Determination of the charge recombination pathway of D+QAQ(-)B and free energy and kinetic relations between Q(-)AQB and QAQ(-)B.

TL;DR: The electron-transfer reactions and thermodynamic equilibria involving the quinone acceptor complex in bacterial reaction centers from R. sphaeroides were investigated and it was found that the charge recombination pathway of D+QAQ(-)B proceeds via the intermediate state D-AQB, the direct pathway contributing less than approx.
