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.

ferredoxin

(fĕr′ĭ-dŏk′sĭn)
n.
An iron-containing protein present in green plants and certain anaerobic bacteria that functions in electron transport reactions in biochemical processes, such as photosynthesis.

ferredoxin

an important iron-containing protein acting as an electron carrier in the ELECTRON TRANSPORT SYSTEM that operates in the LIGHT REACTIONS of PHOTOSYNTHESIS, particularly in NONCYCLIC PHOTOPHOSPHORYLATION.
