This review is focused on reactions that gate (control) the electron transfer between the primary quinone QA and secondary quinone QB in the photosynthetic reaction centre of Rhodobacter sphaeroides. The results on electron and proton transfer are discussed in relation to structural information and to the steered molecular dynamics simulations of the QB ring flip in its binding pocket. Depending on the initial position of QB in the pocket and on certain conditions, the rate of electron transfer is suggested to be limited either by the quinone ring flip or by the charge-compensating proton equilibration between the surface and the buried QB site.
