Subunit and chlorophyll organization of the plant photosystem II supercomplex

Abstract: Photosystem II (PSII) is a light-driven protein, involved in the primary reactions of photosynthesis. In plant photosynthetic membranes PSII forms large multisubunit supercomplexes, containing a dimeric core and up to four light-harvesting complexes (LHCs), which act as antenna proteins. Here we solved a three-dimensional (3D) structure of the CSM supercomplex from Arabidopsis thaliana using cryo-transmission electron microscopy (cryo-EM) and single-particle analysis at an overall resolution of 5.3 Å. Using a … Show more

“…LHCB6 has previously been assigned photoprotection properties (de Bianchi et al, 2008;Passarini et al, 2009), and molecular dynamics simulations for phosphorylated antenna support that conformational changes occur as a consequence of phosphorylation (Ding et al, 2014). Further, LHCB6 position within plant PSII SC suggests that it can mediate specific interactions and possibly energy transfer with other complexes (Nosek et al, 2017;van Bezouwen et al, 2017). Phospho-LHCB6 in P. patens is part of the C 2 S 2 M( 2 ) PSII SC (SC1 and SC2; Fig.…”

“…However, because the design of PSII allows protection for most of its protein components and damage mainly occurs at the reaction center D1 protein (coded by the psbA gene) through production of various radicals and active oxygen species (Baena‐González & Aro, ; Mulo, Sakurai, & Aro, ), repair of PSII requires a fast turnover of the D1 protein and thus may explain the extremely high expression level of psbA relative to psbO . As a consequence, the stoichiometric relationship between the two partner gene products psbA/psbO—being accompanied by additional 20 to 23 protein subunits in PSII (Van Bezouwen et al, )—could be considered far more relaxed than the tight 1:1 one in the rbcL / rbcS system.…”

“…For many photosynthetic complexes, reference structures are available from angiosperms or even A. thaliana itself, but other complexes required use of structures from anciently divergent species, including bacteria and mammals (File S1), making inference of residue homology tenuous. Furthermore, even when structures from close relatives were available, they were sometimes known to be missing certain subunits ( van Bezouwen, et al 2017;Laughlin, et al 2019). Therefore, we did not analyze many subunits within these complexes because of their absence from reference structures or low level of sequence similarity, designating them simply as not available ("NA").…”
