Tuning cofactor redox potentials: the 2-methoxy dihedral angle generates a redox potential difference greater than 160 mV between the primary (Q(A)) and secondary (Q(B)) quinones of the photosynthetic reaction center
Only quinones with a 2-methoxy group can act simultaneously as the primary (Q(A)) and secondary (Q(B)) electron acceptors in photosynthetic reaction centers from Rb. sphaeroides. (13)C HYSCORE measurements of the 2-methoxy in the semiquinone states, SQ(A) and SQ(B), were compared with QM calculation...
