Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

FEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Phage ϕC2 mediates transduction of Tn6215, encoding erythromycin resistance, between Clostridium difficile strains [PDF]

, 2013
UNLABELLED: In this work, we show that Clostridium difficile phage ϕC2 transduces erm(B), which confers erythromycin resistance, from a donor to a recipient strain at a frequency of 10(-6) per PFU.

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

Advanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

Lysogeny In Coagulase-Negative Staphylococci [PDF]

Journal of Medical Microbiology, 1971
Summary Lysogenicity in coagulase-negative staphylococci was tested by incubating the strains in the presence of Mitomycin C. Among 173 strains examined, 45 were found to release phage. Twenty-eight of these phages were obtained from 90 strains belonging to Staphylococcus epidermidis biotype 1 (Baird-Parker, 1965).

From Linear Genes to Epigenetic Inheritance of Three-dimensional Epigenomes [PDF]

, 2011
Fifty years ago Jacob and Monod reported their findings on the regulation of gene activity. Working on lambda bacteriophage lysogeny and the regulation of the production of an enzyme that cleaves lactose, they observed that its production was induced by ...

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors

Advanced Materials Interfaces, EarlyView.
This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...
