This text is an updated record of the most recent insight into the structure/function relationship of reaction centres from photosynthetic bacteria. It addresses in particular, interactions and dynamics which determine the ultra-high quantum yield of photo-induced charge separation in these energy-transforming molecular machines. Of particular interest is the still controversial issue of the primary charge separation mechanism as well as the effects of well-defined modifications, introduced either by mutagenic replacements in the protein matrix or by chemical exchange of reaction centre pigments. Also described are the methods used for the characterization of interactions and dynamics important for electron transfer processes in the reaction centre.
