Large‐Diameter DNA‐Scaffolded Nanopores Enabled by Loosely Packed Peptides for Single‐Molecule Sensing

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
A nanopore composed of transmembrane peptides and a DNA scaffold that assists peptide assembly was constructed. By employing peptides containing the unnatural amino acid 2‐aminoisobutyric acid (Aib), which promotes loose packing between helices, a large‐diameter nanopore was achieved.

Characterization of Interstrand DNA–DNA Cross-Links Using the α-Hemolysin Protein Nanopore [PDF]

ACS Nano, 2015
Nanopore-based sensors have been studied extensively as potential tools for DNA sequencing, characterization of epigenetic modifications such as 5-methylcytosine, and detection of microRNA biomarkers. In the studies described here, the α-hemolysin protein nanopore embedded in a lipid bilayer was used for the detection and characterization of ...

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate

Mycobacterial tlyA gene product is localized to cell-wall without signal sequence.

Frontiers in Cellular and Infection Microbiology, 2015
The mycobacterial tlyA gene product, Rv1694 (MtbTlyA), has been annotated as 'hemolysin' which was re-annotated as 2'-O rRNA methyl transferase. In order to function as a hemolysin, it must reach extracellular milieu with the help of signal sequence(s ...

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...

Actinomycin Derivatives: Structural Diversification and Biological Activities

ChemMedChem, Volume 21, Issue 15, 14 August 2026.
Actinomycins are chromopeptide antibiotics exhibiting remarkable structural diversity and broad bioactivity. This review traces their development from naturally occurring D‐, X‐, A‐, G‐, Y‐, and Z‐type analogs to precursor‐directed, synthetic, and semisynthetic derivatives.

From Fish Waste to Stable Omega‐3 Bioactive Lipids: Encapsulation Strategies and a Conceptual Framework for Antioxidant and Antimicrobial Functional Food Fortification

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Fish waste is valorized into omega‐3‐rich bioactive lipids (EPA and DHA), followed by stabilization through advanced encapsulation technologies to prevent oxidation and improve storage stability. Encapsulation protects polyunsaturated fatty acids from oxidation, improves storage stability, enables controlled gastrointestinal release, and enhances ...
