1.97.1.12	Mg2+	variations in the luminal Mg(II) concentration may modulate the binding between plastocyanin and photosystem I subunit PsaF during the light-dark transitions, being stronger in the illuminated state. The Mg(II) ion probably is bound close to Glu43 in the lower acidic patch, and most likely in the form of a hexaquo complex embedded within the hydration shell of plastocanin, suggesting a specific binding site for Mg(II) that may regulate the binding of plastocyanin to photosystem 1 in vivo	Spinacia oleracea
