Fig. 3: Structures and pigment-binding sites of AcpPCIs.
From: Architecture of symbiotic dinoflagellate photosystem I–light-harvesting supercomplex in Symbiodinium
The structures and arrangements of AcpPCIs (sea green) viewed from stromal side (a) and lumenal side (b). The long termini of AcpPCIs and AB-loop of AcpPCI-10 are colored red. c Structural comparison of 13 AcpPCIs. The long terminal loops of AcpPCIs and AB-loop of AcpPCI-10 are indicated by red arrows. d Superposition of the Chl sites of all AcpPCIs viewed from the stromal side. P1/3/7/8/9 represent AcpPCI-1/3/7/8/9. e Superposition of the carotenoid sites of all ACPIs viewed from the stromal side. Colors for the AcpPCIs and their pigments in (c, d, e) are in line with those in Fig. 1.
