Balancing chloroplast redox status – regulation of FNR binding and release [PDF]

, 2012
Working in synchrony, photosynthetic charge separation, electron transfer, and redox reactions generate proton motive force necessary for the synthesis of ATP and funneling of electrons toward stromal reducing equivalent NADPH.

NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth [PDF]

, 2019
NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide.

New insights into the function and molecular mechanisms of Ferredoxin-NADP+ reductase from Brucella ovis.

Archives of Biochemistry and Biophysics
Bacterial ferredoxin(flavodoxin)-NADP+ reductases (FPR) primarily catalyze the transfer of reducing equivalents from NADPH to ferredoxin (or flavodoxin) to provide low potential reducing equivalents for the oxidoreductive metabolism.

Endophytic Biostimulant Pyrroloquinoline Quinone Enhances Banana Growth and Primes Immunity Against Fusarium Wilt

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Pyrroloquinoline quinone (PQQ) is a redox cofactor derived from prokaryotes that participates in various biological processes involving dehydrogenase enzymes. Previous field trials identified a PQQ‐producing endophyte, Burkholderia seminalis 869T2, which enhances banana growth and reduces Fusarium wilt incidence from 24.5% to 3.4%.

Toward Sustainability: Intensification of Light‐Driven Whole Cell Biocatalysis

ChemBioChem, Volume 27, Issue 8, April 2026.
Whole‐cell, light‐driven biotransformations in photoautotrophic microorganisms offer the potential for higher atom economy by directly harnessing reducing equivalents and oxygen generated through natural photosynthesis. Current advances include the development of strains with improved growth rates and reactor designs that mitigate self‐shading ...

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Unveiling the Role of Rumen Microbiome in Modulating Intramuscular Fat Deposition of Pingliang Red Cattle

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
This study revealed that rumen microbiota significantly influence IMF deposition in Pingliang Red cattle through taxonomic and functional mechanisms. Limosilactobacillus panis and Fibrobacter succinogenes were identified as potential biomarkers for high IMF content.

Towards the competent conformation for catalysis in the ferredoxin-NADP+ reductase from the Brucella ovis pathogen.

Biochimica et Biophysica Acta - Bioenergetics, 2019
Brucella ovis encodes a bacterial subclass 1 ferredoxin-NADP(H) reductase (BoFPR) that, by similarity with other FPRs, is expected either to deliver electrons from NADPH to the redox-based metabolism and/or to oxidize NADPH to regulate the soxRS regulon ...
