ferredoxin

 [fer″ĕ-dok´sin]
a nonheme iron-containing protein having a very low oxidation-reduction potential; the ferredoxins participate in electron transport in photosynthesis, nitrogen fixation, and various other biological processes.

Iron is an essential activator for enzyme-catalysing reactions involving chlorophyll synthesis and for ferrodoxin nitrate reductase [29].
In the upper pathway, hydroxylation of an aromatic ring to a cis-dihydrodiol is catalyzed by dioxygenase, a multicomponent enzyme consisting of reductase, ferrodoxin, and large and small iron-sulfur proteins (ISP).
The differences observed in iron content among plant organs are due to the fact that much of the iron in leaves is associated with the ferrodoxins required for photosynthesis as part of the reverse tricarboxylic acid cycle [26].
