Trapped Conformational States of Semiquinone (D(+•)Q(B)(−•)) Formed by B-Branch Electron Transfer at Low Temperature in Rhodobacter sphaeroides Reaction Centers

The reaction center (RC) from Rhodobacter sphaeroides captures light energy by electron transfer between quinones Q(A) and Q(B), involving a conformational gating step. In this work, conformational states of D(+•)Q(B)(−•) were trapped (80K) and studied using EPR spectroscopy in mutant RCs that lack...
