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

a nonheme protein containing equal amounts of iron and sulfur. Ferredoxins are involved in electron transport in photosynthesis and nitrogen fixation.
