Abstract
Abstract In this Minireview, we describe the function of the bacterial reaction centre (RC) as the central photosynthetic energy‐conversion unit by ultrafast spectroscopy combined with structural analysis, site‐directed mutagenesis, pigment exchange and theoretical modelling. We show that primary energy conversion is a stepwise process in which an electron is transferred via neighbouring chromophores of the RC. A well‐defined chromophore arrangement in a rigid protein matrix, combined with optimised energetics of the different electron carriers, allows a highly efficient charge‐separation process. The individual molecular reactions at room temperature are well described by conventional electron‐transfer theory.
