Roles of Ferredoxin-NADP⁺ Oxidoreductase and Flavodoxin in NAD(P)H-Dependent Electron Transfer Systems

Antioxidants, 2022
Distinct isoforms of FAD-containing ferredoxin-NADP+ oxidoreductase (FNR) and ferredoxin (Fd) are involved in photosynthetic and non-photosynthetic electron transfer systems.

Mechanism of cyanobacterial ferredoxin-dependent flavin thioredoxin reductase reveals thiolate-FAD charge transfer and catalytic asymmetry in a homodimer. [PDF]

FEBS J
Ferredoxin‐dependent flavin thioredoxin reductases (FFTRs) regenerate reduced thioredoxin, sustaining dithiol–disulfide exchange reactions that regulate protein activity in select organisms. In cyanobacterial FFTRs, we describe the formation of a thiolate–flavin charge transfer complex, asynchronous reduction of the two FAD cofactors within the ...

Light driven CO2 fixation by using cyanobacterial photosystem I and NADPH-dependent formate dehydrogenase. [PDF]

PLoS ONE, 2013
The ultimate goal of this research is to construct a new direct CO2 fixation system using photosystems in living algae. Here, we report light-driven formate production from CO2 by using cyanobacterial photosystem I (PS I).

Inter-Organelle NAD Metabolism Underpinning Light Responsive NADP Dynamics in Plants

Frontiers in Plant Science, 2019
Upon illumination, photosystem I in chloroplasts catalyzes light-driven electron transport from plastocyanin to ferredoxin, followed by the reduction of NADP+ to NADPH by ferredoxin:NADP+ reductase for CO2 fixation.

Antagonistic antimalarial properties of a methoxyamino chalcone derivative and 3-hydroxypyridinones in combination with dihydroartemisinin against Plasmodium falciparum [PDF]

PeerJ, 2023
Background The spread of artemisinin (ART)-resistant Plasmodium falciparum threatens the control of malaria. Mutations in the propeller domains of P. falciparum Kelch13 (k13) are strongly associated with ART resistance.

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.

Molecular and functional characterization of ferredoxin NADP(H) oxidoreductase from Gracilaria chilensis and its complex with ferredoxin

Biological Research, 2017
Backgroud Ferredoxin NADP(H) oxidoreductases (EC 1.18.1.2) (FNR) are flavoenzymes present in photosynthetic organisms; they are relevant for the production of reduced donors to redox reactions, i.e.

Structural and mutational analyses of the Leptospira interrogans virulence-related heme oxygenase provide insights into its catalytic mechanism.

PLoS ONE, 2017
Heme oxygenase from Leptospira interrogans is an important virulence factor. During catalysis, redox equivalents are provided to this enzyme by the plastidic-type ferredoxin-NADP+ reductase also found in L. interrogans.

Molecular Catalysis in “Green” Hydrogen Production

Frontiers in Catalysis, 2022
Molecular hydrogen (H2) is considered an ideal energy vector and a clean fuel, due to its zero-carbon combustion. Nevertheless, despite hydrogen is the most and one of the most abundant elements in the universe and in earth crust, respectively, it is ...
