The light-absorbing pigments in purple photosynthetic bacteria are organized into two transmembrane pigmentprotein complexes,i.e.the peripheral LH2 complexes and the core LH1-RC complexes.In most species,the light energy is initially captured by LH2 and is then transferred via LH1 to the RC.In this study,the artificial chromatophore was constructed by reconstitution of light-harvesting complex 2(LH2)and core-complex(LH1-RC)from Thermochromatium tepidum in egg phosphatidylcholine(PC)liposome.
