ferredoxin /fer·re·dox·in/ (fer″ĕ-dok´sin) a nonheme iron-containing protein having a very low redox potential; the ferredoxins participate in electron transport in photosynthesis, nitrogen fixation, and various other biological processes.
fer·re·dox·in (fr-dksn)
n.
A protein found in green plants, algae, and anaerobic bacteria, containing iron and labile sulfur in equal amounts, and functioning in electron transport reactions in biochemical processes, such as photosynthesis.

ferredoxin,

Russell and Martin offer yet another piece of circumstantial evidence that life may have emerged from iron sulfide-catalyzed chemistry: Many of the large proteins that drive basic biochemical reactions today--such as ferredoxin, a protein that mediates metabolic reactions--rely on smaller iron sulfur cofactors.
Chan, a chemist at the California Institute of Technology in Pasadena, and his colleagues report their determination of the structure of one of the bacterium's unusual enzymes, aldehyde ferredoxin oxidoreductase (AOR).
