Extended Data Fig. 4: Structural comparison of the PSI3-IsiA18 supercomplexes from Synechococcus 7942 and Synechocystis 6803.
From: Structural basis for energy and electron transfer of the photosystem I–IsiA–flavodoxin supercomplex
(a) The PSI3-IsiA18 supercomplex from Synechococcus 7942 (colored in magenta, yellow and pink for each of three monomers) and the PSI3-IsiA18 supercomplex from Synechocystis 6803 (PDB code 6NWA, colored in green) are superposed on one of the PsaA subunits. 1~6 indicates IsiA-1~6 in each monomer. (b) Enlarged view of one monomer containing PSI core and IsiA-1~6. The shift of IsiAs and the conformational change of PsaL between the two structures are indicated by red arrows.
