Accessory chlorophylls (B A/B ) in bacterial photosynthetic reaction center play a key role in charge‐separation. Although light‐exposed and dark‐adapted bRC crystal structures are virtually identical, the calculated B A redox potentials for one‐electron reduction differ. This can be traced back to different orientations of the B A ester‐group. This tuning ability of chlorophyll redox potentials modulates the electron transfer from SP* to B A .
