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

open access: yesFrontiers 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.

Mechanistic Insight into the Enzymatic Reduction of Truncated Hemoglobin N of Mycobacterium tuberculosis: role of the CD loop and pre-A Motif in electron cycling [PDF]

open access: yes, 2014
Background: The HbN of Mycobacterium tuberculosis carries a potent nitric-oxide dioxygenase activity despite lacking a reductase domain. Results: The NADH-ferredoxin reductase system acts as an efficient partner for the reduction of HbN.

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

open access: yesFrontiers 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.

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

open access: yesPeerJ, 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.

Identification of Sequences Encoding Symbiodinium minutum Mitochondrial Proteins. [PDF]

open access: yes, 2016
The dinoflagellates are an extremely diverse group of algae closely related to the Apicomplexa and the ciliates. Much work has previously been undertaken to determine the presence of various biochemical pathways within dinoflagellate mitochondria ...

Functional Analysis of A Soybean Ferredoxin-NADP Reductase (FNR) Gene in Response to Soybean Mosaic Virus

open access: yesAgronomy, 2021
The Ferredoxin-NADP reductase (FNR) gene plays a significant role in NADPH production, carbon assimilation, antioxidation, and cross-talking between chloroplasts and mitochondria in plants.

The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts [PDF]

open access: yes, 2018
The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, which efficiently reduces 2-Cys ...

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

open access: yesBiological 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.

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

open access: yesFEBS 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 ...
