The Fenna-Matthews-Olson (FMO) antenna complex from the green sulfur bacterium Chlorobaculum (C.) tepidum is an important model protein to study exciton dynamics and excitation energy transfer in photosynthetic complexes. Single point mutations provide an excellent opportunity for the study of exciton structure and interexciton level relaxation. In this bacterium, the energy harvested by chlorosomes is funnelled via the baseplate pigments and FMO trimers to the reaction center (RC), where photochemistry takes place. The structure of the FMO protein from C. tepidum was solved and revealed a homotrimeric complex containing eight bacteriochlorophylls (BChl) a per monomer.
