Journal ArticleDOI
Native structure of photosystem II at 1.95 Å resolution viewed by femtosecond X-ray pulses.
Michihiro Suga,Fusamichi Akita,Kunio Hirata,Go Ueno,Hironori Murakami,Yoshiki Nakajima,Tetsuya Shimizu,Keitaro Yamashita,Masaki Yamamoto,Hideo Ago,Jian Ren Shen +10 more
TL;DR: A ‘radiation-damage-free’ structure of PSII from Thermosynechococcus vulcanus in the S1 state is reported, and it is expected that this structure will provide a blueprint for the design of artificial catalysts for water oxidation.
Journal ArticleDOI
Light-induced structural changes and the site of O=O bond formation in PSII caught by XFEL.

TL;DR: The structural changes in PSII induced by two-flash illumination at room temperature at a resolution of 2.35 Å are described, providing a mechanism for the O=O bond formation consistent with that proposed previously.
Journal ArticleDOI
An oxyl/oxo mechanism for oxygen-oxygen coupling in PSII revealed by an x-ray free-electron laser
Michihiro Suga,Michihiro Suga,Fusamichi Akita,Fusamichi Akita,Keitaro Yamashita,Yoshiki Nakajima,Go Ueno,Hongjie Li,Hongjie Li,Takahiro Yamane,Kunio Hirata,Yasufumi Umena,Shinichiro Yonekura,Long Jiang Yu,Hironori Murakami,Takashi Nomura,Tetsunari Kimura,Minoru Kubo,Seiki Baba,Takashi Kumasaka,Kensuke Tono,Makina Yabashi,Hiroshi Isobe,Kizashi Yamaguchi,Masaki Yamamoto,Hideo Ago,Jian Ren Shen +26 more
TL;DR: To reveal the mechanism of water oxidation, structures of PSII in the S1, S2, and S3 states by x-ray free-electron laser serial crystallography reveal details of photosynthetic oxygen evolution.
Journal ArticleDOI
High-resolution cryo-EM structure of photosystem II reveals damage from high-dose electron beams
Koji Kato,Naoyuki Miyazaki,Tasuku Hamaguchi,Yoshiki Nakajima,Fusamichi Akita,Koji Yonekura,Jian Ren Shen +6 more
TL;DR: In this paper, the structure of photosystem II (PSII) in solution at 1.95 µm resolution was analyzed by single-particle cryo-electron microscopy (cryo-EM).
Journal ArticleDOI
Thylakoid membrane lipid sulfoquinovosyl-diacylglycerol (SQDG) is required for full functioning of photosystem II in Thermosynechococcus elongatus
Yoshiki Nakajima,Yasufumi Umena,Ryo Nagao,Kaichiro Endo,Koichi Kobayashi,Fusamichi Akita,Fusamichi Akita,Michihiro Suga,Hajime Wada,Takumi Noguchi,Jian Ren Shen +10 more
TL;DR: The present results suggest that although SQDD binding in all of the PSII-binding sites is necessary to fully maintain the activity and stability of PSII, replacement of SQDG by other lipids can partially compensate for their functions.
