Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions
Advanced Science, Volume 12, Issue 46, December 11, 2025.Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.

Anaerobic Limonene Metabolism in a Methanogenic Enrichment Involves a Glycine Radical Enzyme
Environmental Microbiology, Volume 27, Issue 11, November 2025.A methanogenic enrichment culture on the natural monoterpene limonene is characterised by a novel glycine radical enzyme for anaerobic hydrocarbon activation, the presence of a microbial loop for necromass utilisation and the presence of a predator of Bacteria and Archaea. ABSTRACT Limonene is a natural monoterpene omnipresent in human environments. It

Expansion of cagA Copy Number in Helicobacter pylori During Co‐Infection in a Mouse Model
Helicobacter, Volume 30, Issue 6, November/December 2025.ABSTRACT Introduction The virulence factor CagA is critical in mediating inflammation, and Helicobacter pylori PMSS1 dynamically modulates cagA copy number in response to host immune pressure. Co‐infection with Salmonella enterica serotype Typhimurium has been shown to heighten systemic inflammation and reduce H.

Cobamide Fingerprinting Reveals Nutritional Diversity of Vitamin B12 in Edible Shellfish
FishesIn edible shellfish, vitamin B12 content has traditionally been evaluated based on total content; however, recent studies reveal substantial diversity in corrinoid composition among species. This review integrates molecular and ecological perspectives to

Porphyrin and corrinoid mutants of Bacillus subtilis [PDF]
Journal of Bacteriology, 1977 Porphyrin auxotrophs of Bacillus subtilis can be divided into two groups. Strains belonging to the first group (hemA, hemB, or hemC) are not able to synthesize or metabolize porphobilinogen. These strains require cysteine, cystine, and methionine, respectively.

Complex Formation with the Activator RACo Affects the Corrinoid Structure of CoFeSP
, 2016 Activation of the corrinoid [Fe-S] protein (CoFeSP), involved in reductive CO2 conversion, requires the reduction of the Co(II) center by the [Fe-S] protein RACo, which according to the reduction potentials of the two proteins would correspond to an ...
