Redox potential of quinones in photosynthetic reaction centers from Rhodobacter sphaeroides: dependence on protonation of Glu-L212 and Asp-L213.

Biochemistry - 8 Apr 2003

Ishikita Hiroshi, Morra Giulia, Knapp Ernst-Walter

Abstract excerpt

The absolute values of the one-electron redox potentials of the two quinones (Q(A) and Q(B)) in bacterial photosynthetic reaction centers from Rhodobacter sphaeroides were calculated by evaluating the electrostatic energies from the solution of the linearized Poisson-Boltzmann equation at pH 7.0. The redox potential for Q(A) was calculated to be between -173 and -160 mV, which is close to the lowest measured...
