Authors: Kazutoshi Tani / Ryo Kanno / Yuki Makino / Malgorzata Hall / Mizuki Takenouchi / Michie Imanishi / Long-Jiang Yu / Jörg Overmann / Michael T Madigan / Yukihiro Kimura / Akira Mizoguchi / ...Authors: Kazutoshi Tani / Ryo Kanno / Yuki Makino / Malgorzata Hall / Mizuki Takenouchi / Michie Imanishi / Long-Jiang Yu / Jörg Overmann / Michael T Madigan / Yukihiro Kimura / Akira Mizoguchi / Bruno M Humbel / Zheng-Yu Wang-Otomo / Abstract: The light-harvesting-reaction center complex (LH1-RC) from the purple phototrophic bacterium Thiorhodovibrio strain 970 exhibits an LH1 absorption maximum at 960 nm, the most red-shifted absorption ...The light-harvesting-reaction center complex (LH1-RC) from the purple phototrophic bacterium Thiorhodovibrio strain 970 exhibits an LH1 absorption maximum at 960 nm, the most red-shifted absorption for any bacteriochlorophyll (BChl) a-containing species. Here we present a cryo-EM structure of the strain 970 LH1-RC complex at 2.82 Å resolution. The LH1 forms a closed ring structure composed of sixteen pairs of the αβ-polypeptides. Sixteen Ca ions are present in the LH1 C-terminal domain and are coordinated by residues from the αβ-polypeptides that are hydrogen-bonded to BChl a. The Ca-facilitated hydrogen-bonding network forms the structural basis of the unusual LH1 redshift. The structure also revealed the arrangement of multiple forms of α- and β-polypeptides in an individual LH1 ring. Such organization indicates a mechanism of interplay between the expression and assembly of the LH1 complex that is regulated through interactions with the RC subunits inside. | |||||||||||||||||||||
