fer·re·dox·ins

(fer'ĕ-dok'sinz),
Proteins containing iron-sulfur complexes and displaying electron-carrier activity but no classical enzyme function. Ferredoxins are found in green plants, algae, anaerobic bacteria, and in mitochondria from the adrenal cortex and heart muscle. They are involved in several oxidation-reduction reactions in living organisms (for example, nitrogen fixation).

fer·re·dox·ins

(fer'ĕ-dok'sinz)
Proteins containing iron and (labile) sulfur in equal amounts, displaying electron-carrier activity but no classical enzyme function. Ferredoxins are found in green plants, algae, and anaerobic bacteria, and are involved in several oxidation-reduction reactions in living organisms (e.g., nitrogen fixation).

2009) The iron hydrogenase of Thermotoga maritima utilizes ferredoxin and NADH synergistically: a new perspective on anaerobic hydrogen production.
Consistent with this idea, multiple hydrogenosomal fermentation enzymes--including ferredoxin, succinyl-CoA synthetase, and malic enzyme--resemble their counterparts in mitochondria (Johnson et al.
An iron-dependent hydrogenase (Fe-hydrogenase), which gives the hydrogenosome its name, transfers electrons from reduced ferredoxin to two protons to make hydrogen gas (Lindmark and Muller, 1973; Muller, 1993; Payne et al.
The reduced ferredoxin is produced within the hydrogenosome by pyruvate:ferredoxin oxidoreductase (PFOR), which decarboxylates pyruvate to acetyl-CoA and [CO.
