Fantastic [FeFe]-Hydrogenases and Where to Find Them

Frontiers in Microbiology, 2022
[FeFe]-hydrogenases are complex metalloenzymes, key to microbial energy metabolism in numerous organisms. During anaerobic metabolism, they dissipate excess reducing equivalents by using protons from water as terminal electron acceptors, leading to ...

FdC1 and Leaf-Type Ferredoxins Channel Electrons From Photosystem I to Different Downstream Electron Acceptors

Frontiers in Plant Science, 2018
Plant-type ferredoxins in Arabidopsis transfer electrons from the photosystem I to multiple redox-driven enzymes involved in the assimilation of carbon, nitrogen, and sulfur.

The semiquinone swing in the bifurcating electron transferring flavoprotein/butyryl-CoA dehydrogenase complex from Clostridium difficile

Nature Communications, 2017
The electron-transferring flavoprotein / butyryl-CoA dehydrogenase (EtfAB/Bcd) complex catalyzes the reduction of crotonyl-CoA and ferredoxins by NADH in anaerobic microbes.

Carbon Fixation in the Chemolithoautotrophic Bacterium Aquifex aeolicus Involves Two Low-Potential Ferredoxins as Partners of the PFOR and OGOR Enzymes

Life, 2023
Aquifex aeolicus is a microaerophilic hydrogen- and sulfur -oxidizing bacterium that assimilates CO2 via the reverse tricarboxylic acid cycle (rTCA). Key enzymes of this pathway are pyruvate:ferredoxin oxidoreductase (PFOR) and 2-oxoglutarate:ferredoxin ...

Ferredoxin from Bacillus polymyxa

Biochemical and Biophysical Research Communications, 1971
A ferredoxin has been purified from Bacillus polymyxa, strain Hino, a facultative N2-fixing organism. Optical and electron spin resonance spectra of the ferredoxin have been recorded, and its molecular weight is approximately 9,000. The ferredoxin is reduced reversibly by H2 in the presence of hydrogenase from Clostridium pasteurianum or B.

Ferredoxin—ferredoxin NADP reductase interaction [PDF]

FEBS Letters, 1984
Ferredoxin‐NADP reductase (FNR) and ferredoxin form a complex when the former is membrane‐bound as they do when both components are in solution, with the same dissociation constant. The rate constant of NADP photoreduction, first order with respect to the complex, is more than 20‐times higher when FNR is membrane‐bound than when the enzyme is in ...
