Extended Data Fig. 3: Cryo-EM densities and structural models of the PSII core intrinsic, extrinsic subunit and various cofactors of the Psb28-RC47 complex (a) and Psb28-PSII complex (b).

The intrinsic subunits and extrinsic subunit are shown as mixed cartoon/stick model. All cofactors are shown as stick models. Fe and Mg are shown as magenta and green spheres respectively. The cryo-EM density map of each subunit is depicted in gray meshes.
