Skin-associated Corynebacterium amycolatum shares cobamides [PDF]

mSphere
The underlying interactions that occur to maintain skin microbiome composition, function, and overall skin health are largely unknown. Often, these types of interactions are mediated by microbial metabolites.

Site-specific incorporation of 19F-nuclei at protein C-terminus to probe allosteric conformational transitions of metalloproteins [PDF]

Communications Biology
Allosteric conformational change is an important paradigm in the regulation of protein function, which is typically triggered by the binding of small cofactors, metal ions or protein partners.

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

J Sci Food Agric
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.

Evidence for corrin biosynthesis in the last universal common ancestor. [PDF]

FEBS J
Cobalamin biosynthesis can be traced back to the last universal common ancestor. After a stage of chemical evolution of the acetyl‐CoA pathway, the enzymatic synthesis of cobalamin evolved, allowing life to be independent of the insoluble solid‐state catalysts that tethered primordial CO2 assimilation to the Earth's crust, suggesting a role for corrin ...

Expansion of cagA Copy Number in Helicobacter pylori During Co-Infection in a Mouse Model. [PDF]

Helicobacter
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.

Phylogenetic distribution and experimental characterization of corrinoid production and dependence in soil bacterial isolates

bioRxiv, 2023
Soil microbial communities impact carbon sequestration and release, biogeochemical cycling, and agricultural yields. These global effects rely on metabolic interactions that modulate community composition and function.
