The term "ferredoxin" was coined by D.C. Wharton of the DuPont Co. and applied to the "iron protein" first purified in 1962 by Mortenson, Valentine, and Carnahan from the anaerobic bacterium Clostridium pasteurianum. (wikipedia.org)
Oxidoreductase2
It accepts electrons produced from sunlight-excited chlorophyll and transfers them to the enzyme ferredoxin: NADP+ oxidoreductase EC 1.18.1.2. (wikipedia.org)
The pulse of acetogenesis appears to have been collectively catalyzed by a number of different organisms and metabolisms, most prominently pyruvate:ferredoxin oxidoreductase. (frontiersin.org)
Protein3
Depending on the sequence of the supporting protein ferredoxins have reduction potential from around -500mv to -340 mV. (wikipedia.org)
The Rnf complex is a widespread membrane protein in bacteria that reversibly transfers electrons between NADH and ferredoxin while pumping Na+ or H+ ions across the membrane. (wikipedia.org)
Ferredoxin can also be reduced by using NADH (-320 mV) or H 2 (-414 mV), but these processes are coupled to the consumption of the membrane potential to power the "boosting" of electrons to the higher energy state. (wikipedia.org)
Sulfur4
Ferredoxins (from Latin ferrum: iron + redox, often abbreviated "fd") are iron-sulfur proteins that mediate electron transfer in a range of metabolic reactions. (wikipedia.org)
Ferredoxins are small proteins containing iron and sulfur atoms organized as iron-sulfur clusters. (wikipedia.org)
Ferredoxins can be classified according to the nature of their iron-sulfur clusters and by sequence similarity. (wikipedia.org)
Fd− red However a few bacterial ferredoxins (of the 2[4Fe4S] type) have two ironsulfur clusters and can carry out two electron transfer reactions. (wikipedia.org)
Electron4
In non-cyclic photophosphorylation, ferredoxin is the last electron acceptor thus reducing the enzyme NADP+ reductase. (wikipedia.org)
In this way, ferredoxin acts as an electron transfer agent in biological redox reactions. (wikipedia.org)
Ferredoxins typically carry out a single electron transfer. (wikipedia.org)
A single cell can have multiple types of ferredoxins where each type is tuned to optimally carry out different reactions. (wikipedia.org)
Highly1
The highly reducing ferredoxins are reduced either by using another strong reducing agent, or by using some source of energy to "boost" electrons from less reducing sources to the ferredoxin. (wikipedia.org)
Ferredoxins (from Latin ferrum: iron + redox, often abbreviated "fd") are iron-sulfur proteins that mediate electron transfer in a range of metabolic reactions. (wikipedia.org)
The chloroplast ferredoxin is involved in both cyclic and non-cyclic photophosphorylation reactions of photosynthesis. (wikipedia.org)
