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.

Cobalamin‐Dependent Aryl Methyl Ether O‐Demethylases: Promising Enzymes for Biocatalytic Applications from Lignin Valorization to Organic Synthesis

ChemCatChem, Volume 17, Issue 21, November 10, 2025.
Cobalamin‐dependent aryl methyl ether O‐demethylases have high potential for biocatalytic applications, including lignin valorization and synthetic chemistry. In this review, we provide a detailed overview of such O‐demethylase systems identified to date from various microorganisms, including their mechanism, substrate scope and selectivity, and ...

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.

Pseudovitamin B12 producing Loigolactobacillus coryniformis enhances soy milk fermentation by Lactobacillus delbrueckii subsp. bulgaricus

Journal of the Science of Food and Agriculture, Volume 105, Issue 10, Page 5239-5245, 15 August 2025.
Abstract BACKGROUND Fermenting soy milk with lactic acid bacteria is challenging. Generally, carbohydrates are added to enhance the acid production in soy milk. However, the yoghurt starter Lactobacillus delbrueckii subsp. bulgaricus did not succeed in fermenting soy milk supplemented with carbohydrates.

Acetylene Fuels TCE Reductive Dechlorination by Defined Dehalococcoides/Pelobacter Consortia. [PDF]

, 2017
Acetylene (C2H2) can be generated in contaminated groundwater sites as a consequence of chemical degradation of trichloroethene (TCE) by in situ minerals, and C2H2 is known to inhibit bacterial dechlorination. In this study, we show that while high C2H2 (

Evolutionary Trajectories of Methionine Metabolism in Mycobacterium and Its Application to Engineer a Vitamin B12 Whole‐Cell Ribosensor

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
Molecular and functional experiments highlight the relevance of species‐specific polymorphisms in a B12 riboswitch of the Mycobacterium genus. This information provided proof‐of‐concept to engineer a whole‐cell biosensor capable of detecting vitamin B12. ABSTRACT Vitamin B12 metabolism differs among members of the Mycobacterium genus.
