The Role of the [2Fe‐2S] Cluster of Escherichia coli IscR in Responding to Redox‐Cycling Agents
Molecular Microbiology, Volume 124, Issue 5, Page 433-448, November 2025.Redox cycling agents like phenazine methosulfate (PMS) are known for upsetting cellular redox balance. Here we describe how PMS leads to upregulation of the ISC and SUF Fe‐S cluster biogenesis pathways in Escherichia coli when PMS oxidizes the [2Fe‐2S]1+ cluster of the transcription factor IscR, thereby derepressing the operon encoding ISC and, when a ...

The FEBS Journal, Volume 292, Issue 20, Page 5491-5505, October 2025.The membrane‐bound heme flavoprotein MsrQ is the specific electron donor for the periplasmic methionine sulfoxide reductase MsrP. Analysis of its flavin environment revealed that ubiquinone (UQ) is a cofactor for MsrQ. However, redox studies demonstrate that UQ cannot function as an electron donor for the MsrPQ system.

Molecular Microbiology, Volume 124, Issue 4, Page 297-309, October 2025.The periplasmic multicopper oxidase CueO oxidizes cuprous ions (Cu+) to cupric ions (Cu2+), a well‐known process typically coupled with oxygen reduction. In this study, we report unexpected anaerobic phenotypes associated with CueO, suggesting that it may use an alternative electron acceptor in the absence of oxygen.

Molecular Nutrition &Food Research, Volume 69, Issue 17, September 2025.We have shed light on the mode of action behind the postbiotic form of Bifidobacterium breve NCC 2950. Heat treatment of this strain at 90°C leads to the production of 4‐oxo‐2‐pentenoic acid (OPA), which activates NRF2 host response, improving oxidative stress resistance and decreasing inflammation. ABSTRACT Postbiotics are defined as a “preparation of

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation
Frontiers in Microbiology, 2015 At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are

The incorporation of labeled lysine into the proteins of guinea pig liver homogenate [PDF]
, 1949 When C14-labeled lysine is incubated with guinea pig liver homogenate, α-aminoadipic, α-ketoadipic, and glutaric acids are formed from the lysine (1). These transformations were established by finding the radioactivity of the C14 tracer in the metabolic ...
