紫色光合细菌利用色素-蛋白质复合体获取光线，这种复合体通常排列在被称为计时器的伪细胞器中。基于原子力显微镜数据，建立了光度红螺菌的生色团模型。通过分子动力学模拟和量子动力学计算表征了络合物间的激发转移网络，并探讨了紧密堆积和捕光效率之间的相互作用。
Purple photosynthetic bacteria harvest light using pigment-protein complexes which are often arranged in pseudo-organelles called chronnatophores. A model of a chromatophore from Rhodospirillum photometricum was constructed based on atomic force microscopy data. Molecular-dynamics simulations and quantum-dynamics calculations were performed to characterize the intercomplex excitation transfer network and explore the interplay between close-packing and light-harvesting efficiency.
