ジャーナル: Science / 年: 2018 タイトル: Structure of the maize photosystem I supercomplex with light-harvesting complexes I and II. 著者: Xiaowei Pan / Jun Ma / Xiaodong Su / Peng Cao / Wenrui Chang / Zhenfeng Liu / Xinzheng Zhang / Mei Li / 要旨: Plants regulate photosynthetic light harvesting to maintain balanced energy flux into photosystems I and II (PSI and PSII).

Under light conditions favoring PSII excitation, the PSII antenna, light-harvesting complex II (LHCII), is phosphorylated and forms a supercomplex with PSI core and the PSI antenna, light-harvesting complex I (LHCI). Both LHCI and LHCII then transfer excitation energy to the PSI core. We report the structure of maize PSI-LHCI-LHCII solved by cryo-electron microscopy, revealing the recognition site between LHCII and PSI. The PSI subunits PsaN and PsaO are observed at the PSI-LHCI interface and the PSI-LHCII interface, respectively. Each subunit relays excitation to PSI core through a pair of chlorophyll molecules, thus revealing previously unseen paths for energy transfer between the antennas and the PSI core.
