iMetaOmics, Volume 3, Issue 2, June 2026.The “efficacy paradox” of phytochemicals, low bioavailability yet significant health benefits, is associated with gut microbiota, which biotransforms dietary precursors into bioactive metabolites, enabling systemic effects. Thus, health outcomes of diet depend not just on intake “the rainbow”, but on gut microbial metabolism, redefining “you are what ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Protein sequence surveys show that nickel‐ and molybdenum/copper‐containing carbon monoxide dehydrogenases (CODHs) are widespread in the ocean. Phylogenetic and genome context analyses reveal that marine CODHs are highly diverse in both evolutionary history and functional organisation.

Molecular Microbiology, Volume 125, Issue 6, Page 493-505, June 2026.This study investigates in vivo the role of the flavin reductase Fre as an electron supplier to the periplasmic methionine sulfoxide reductase system MsrPQ. ABSTRACT The MsrPQ system is essential for the repair of oxidized methionine residues in periplasmic proteins, ensuring bacterial resistance to oxidative stress and envelope integrity.

Protein Science, Volume 35, Issue 5, May 2026.Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

A conditional-lethal molybdopterin-defective mutant of barley
Molecular and General Genetics MGG, 1985 The molybdenum cofactor of the barley mutant R9401 is not able to reconstitute NADPH nitrate reductase activity from extracts of the N. crassa nit-1 mutant nor is it able to effect dimerisation of the nitrate reductase subunits present in the R9401 mutant.
