Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Cytoplasmic sulfurtransferases in the purple sulfur bacterium Allochromatium vinosum: evidence for sulfur transfer from DsrEFH to DsrC. [PDF]

PLoS ONE, 2012
While the importance of sulfur transfer reactions is well established for a number of biosynthetic pathways, evidence has only started to emerge that sulfurtransferases may also be major players in sulfur-based microbial energy metabolism.

Characterization of anaerobic sulfite reduction by Salmonella typhimurium and purification of the anaerobically induced sulfite reductase [PDF]

Journal of Bacteriology, 1989
Mutants of Salmonella typhimurium that lack the biosynthetic sulfite reductase (cysI and cysJ mutants) retain the ability to reduce sulfite for growth under anaerobic conditions (E. L. Barrett and G. W. Chang, J. Gen. Microbiol., 115:513-516, 1979). Here we report studies of sulfite reduction by a cysI mutant of S.

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, Volume 82, Issue 7, Page 6387-6398, July 2026.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Sulfite Reductase Activity in Extracts of Various Photosynthetic Bacteria [PDF]

Proceedings of the National Academy of Sciences, 1974
Extracts of representative bacterial strains from the various families of photosynthetic prokaryotes are demonstrated to possess significant levels of sulfite reductase [EC 1.8.99.1; hydrogen-sulfide: (acceptor)oxidoreductase] activity with reduced methyl viologen as electron donor, but not NADPH 2 .

Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

C-Terminal Redox Domain of Arabidopsis APR1 Is a Non-Canonical Thioredoxin Domain with Glutaredoxin Function

Antioxidants, 2019
Sulfur is an essential nutrient that can be converted into utilizable metabolic forms to produce sulfur-containing metabolites in plant. Adenosine 5′-phosphosulfate (APS) reductase (APR) plays a vital role in catalyzing the reduction of activated ...

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.
