a Overall structure of PSI-IsiA viewed from the cytosolic side. Green squared areas are enlarged in panels b–d. b Interactions between IsiA2-1 and PsaA/PsaD (left and right panels). c Interaction between IsiA1-4 and PsaA. d Interaction between IsiA1-4 and PsaA. Interactions are indicated by dashed lines, and the numbers are distances in Å. Amino acid residues and pigments participating in the interactions are labeled; for example, W313/1 means Trp313 in IsiA2-1; a846/A means Chl a 846 in PsaA. BCR, β-carotene.
