The primary events of bacterial photosynthesis rely on the interplay of various specialized protein complexes organized in a supramolecular structure commonly termed the photosynthetic unit (PSU), which consists of the photochemical reaction center and of an associated antenna network. Employing single-molecule spectroscopic techniques we have been able to observe the excitation-energy transfer within a single PSU. From these findings we conclude that the building blocks of the PSU spontaneously form stable, functional aggregates in a non-membrane environment.
