Two ferredoxins, human mitochondrial ferredoxin 1 (FDX1) and human mitochondrial ferredoxin 2 (FDX2), are present in the matrix of human mitochondria. − [10], Some ferredoxins have a sufficiently high redox potential that they can be directly reduced by NADPH. not otherwise permitted to reproduce, republish, redistribute, or sell any Supporting Information It functions as an electron shuttle in the cholesterol side-chain cleavage reaction which … Your Mendeley pairing has expired. [5], Ferredoxin can also be reduced by using NADH (-320mv) or H2 (-414mV), but these processes are coupled to the consumption of the membrane potential to power the "boosting" of electrons to the higher reduction potential.

As a member of the [2Fe-2S] cluster-containing ferredoxin family, Fdx1 reduces mitochondrial cytochrome P450 enzymes, which then catalyze; e.g., the conversion of cholesterol to pregnenolone, aldosterone, and cortisol. [4] When the ratio of reduced:oxidised ferredoxin is around 95%, the cellular reduction potential of around -500 mv can be achieved. One group of ferredoxins, originally found in chloroplast membranes, has been termed "chloroplast-type" or "plant-type" (InterPro: IPR010241).

These results, along with those from cysteine-to-serine mutations in other ferredoxins, provide the basis for a more comprehensive theoretical and practical understanding of the features important to the ligation of [2Fe-2S] clusters, although they do not yet permit determination of which two cysteines ligate Fe(II) and which ligate Fe(III) in the reduced protein. Insiya Fidai, Christine Wachnowsky, J. Low- and high-potential ferredoxins are related by the following redox scheme: The formal oxidation numbers of the iron ions can be [2Fe3+, 2Fe2+] or [1Fe3+, 3Fe2+] in low-potential ferredoxins.
