Promoter recognition by a complex of Spx and the C-terminal domain of the RNA polymerase alpha subunit. [PDF]

open access: yesPLoS ONE, 2010
Spx, an ArsC (arsenate reductase) family member, is a global transcriptional regulator of the microbial stress response and is highly conserved amongst Gram-positive bacteria.

Cyclic 5-Membered Disulfides Are Not Selective Substrates of Thioredoxin Reductase, but Are Opened Nonspecifically

open access: yes, 2022
The cyclic five-membered disulfide 1,2-dithiolane has been used as the key element in numerous chemical biology probes. Contradictory views of this disulfide populate the literature: some reports describe it as being nonspecifically reduced, others as a ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

open access: yesBMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Conformational fluctuations coupled to the thiol-disulfide transfer between thioredoxin and arsenate reductase in Bacillus subtilis

open access: yes, 2007
Arsenic compounds commonly exist in nature and are toxic to nearly all kinds of life forms, which directed the evolution of enzymes in many organisms for arsenic detoxification.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Characterisation of the oxidoreductase Erol-Lß and the misfolding of the secretory pathway substrate HLA-B27 [PDF]

open access: yes, 2007
The endoplasmic reticulum (ER) is the site of oxidative folding for proteins entering the secretory pathway. Here, nascent polypeptides acquire disulfide bonds, which confer both stability and functionality on secretory and ER-resident proteins.

NK-lysin, a Disulfide-containing Effector Peptide of T-lymphocytes, Is Reduced and Inactivated by Human Thioredoxin Reductase

open access: yes, 1996
The cytotoxic and antibacterial polypeptide NK-lysin has a molecular mass of approximately 9 kDa and contains three disulfide bonds. The activity was highly dependent on intact disulfides, because the bactericidal effect on Escherichia coli and the ...

Multiple functions of Nm23-H1 are regulated by oxido-reduction system. [PDF]

open access: yesPLoS ONE, 2009
Nucleoside diphosphate kinase (NDPK, Nm23), a housekeeping enzyme, is known to be a multifunctional protein, acting as a metastasis suppressor, transactivation activity on c-myc, and regulating endocytosis.

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...
