a Distribution of chlorophyll molecules and potential energy transfer pathways at the stromal side layer (left panel) and lumenal side layer (right panel) of RsPSII-CAC complex, viewed from the stromal side. Chls a and c are colored in green and blue. Chlorophylls belonging to different subunits and with Mg-to-Mg distances shorter than 20 Å are shown in bold stick and labeled. Energy transfer pathways within the CAC belts, between the outer and inner CAC belts and from the inner CACs to the PSII core are shown in red, blue, and purple dashed lines, respectively. b Distributions of carotenoid molecules in RsPSII-CAC complex, viewed from the stromal side. Alloxanthin (Alx), crocoxanthin (Cro), and α-carotene (α-Car) are colored in purple, orange, and light blue, respectively.
