Extended Data Fig. 6: Assembly pathway of PSI towards dimer.
From: Algal photosystem I dimer and high-resolution model of PSI-plastocyanin complex

a, Schematic view of known biochemically and structurally defined PSI states and assembling protein subunits. Subunit composition for each state is outlined with the shape of a following state and corresponding color. The divaricating of the assembly pathway takes place at the last stage (red background). The path towards PSI monomer or dimer is dependent on presence/absence of PsaH and Lhca2.
