Characterization of the structural changes and photochemical activity of photosystem I under Al3+ effect

• Inhibitory sites of Al3+ were determined in PSI complex. • Al3+ exerts multiple effects on the electron transport chain of PSI. • Al3+ induces a reduction in the energy transfer from the LHCI to the PSI RC. • Al3+ induced conformational change of the protein secondary structures in PSI. • Structur...

• Inhibitory sites of Al3+ were determined in PSI complex. • Al3+ exerts multiple effects on the electron transport chain of PSI. • Al3+ induces a reduction in the energy transfer from the LHCI to the PSI RC. • Al3+ induced conformational change of the protein secondary structures in PSI. • Structural changes are associated with alterations of PSI photochemical activity.
