Photosynthetic organisms have developed various light-harvesting antenna systems to capture light and transfer energy to reaction centers(RCs).Simultaneous utilization of the integral membrane light-harvesting antenna(LH complex) and the extrinsic antenna(chlorosomes) makes the phototrophic bacterium Chloroflexus(Cfx.) aurantiacus an ideal model for studying filamentous anoxygenic phototrophs(FAPs). Here, we determined the structure of a minimal RC–LH photocomplex from Cfx. aurantiacus J-10-fl(CaRC–LH) at 3.05-? resolution. The CaRC–LH binds only to seven LH subunits, which form a crescent-shaped antenna surrounding the movable menaquinone-10(QB)binding site of Ca RC. In this complex with minimal LH units, an extra antenna is required to ensure sufficient light-gathering, providing a clear explanation for the presence of chlorosomes in Cfx. aurantiacus. More importantly, the semicircle of the antenna represents a novel RC–LH assembly pattern. Our structure provides a basis for understanding the existence of chlorosomes in *** and the possible assembly pattern of RC–LH.
