绿藻莱茵衣藻C2S2M2N2型PSII–LHCII超复合物单颗粒冷冻电镜成像数据集

完整的Cr PSII–LHCII结构展示了高效的能量传输网络。与高等植物PSII的C2S2M2型超复合物相比，M-LHCII的旋转增强了M-LHCII与CP29之间的相互作用和联系，这可能会提高EET从M-LHCII到CP29的效率。此外，N-LHCII和CP29之间的相互作用可能介导N-LHCII与PSII核之间的结合和能量转移。此外，由于N-LHCII和M-LHCII之间的相互作用，M-LHCII收集的能量可能会通过N-LHCII转移到CP29。综上所述，这些特性确保了更有效的EET，绿藻可能需要EET来适应水生环境中的低光照强度。

The complete Cr PSII–LHCII structure reveals an efficient energy transfer (EET) network. Compared with the C2S2M2-type PSII supercomplex from higher plants, the rotation of M-LHCII enhances the interactions and associations between M-LHCII and CP29, which may improve the efficiency of EET from M-LHCII to CP29. Furthermore, the interactions between N-LHCII and CP29 may mediate the binding and energy transfer between N-LHCII and the PSII core. Additionally, owing to the interactions between N-LHCII and M-LHCII, the energy harvested by M-LHCII can be transferred to CP29 via N-LHCII. Collectively, these characteristics ensure more efficient EET, which green algae may require to adapt to low-light intensities in aquatic environments.
