Construction of Phospholipid‐Like Vesicles by Aqueous Aminolysis of Acyl Thioesters With Diamino Acids

Chemistry – A European Journal, Volume 32, Issue 6, 9 February 2026.
Membrane‐forming phospholipids are produced in cells via enzymatic diacylation. Here, we show that direct aminolysis of acyl thioesters with diamino acids in aqueous environments enables the synthesis of diacylated amino acids (DAAAs), which spontaneously self‐assemble into robust phospholipid‐like vesicles across a broad range of pH and temperature ...

A Growth‐Coupled Evolutionary Strategy Enhances Heme Biosynthesis in Saccharomyces cerevisiae

Biotechnology Journal, Volume 21, Issue 1, January 2026.
Graphical Abstract and Lay Summary Introducing a plasmid with a heme‐responsive promoter connected to a growth‐promoting gene into Saccharomyces cerevisiae created a positive feedback loop between intracellular heme levels and cell growth. After 100 h of adaptive evolution, the plasmid was removed, resulting in a mutant strain that exhibited an ...

Shared HLA‐E and Mamu‐E Peptide Repertoires With Subtle Peptide Binding Differences Revealed by Combined nDSF‐ and Fluorescence Polarisation‐Based Methods

European Journal of Immunology, Volume 56, Issue 1, January 2026.
The MHC‐E peptide binding methods described here—nano‐differential scanning fluorimetry and fluorescence polarisation—demonstrate shared peptide binding repertoires with subtle binding hierarchy differences for the tested HLA‐E and Mamu‐E allotypes.

Scientific opinion on the safety and efficacy of concentrated liquid L‐lysine (base), concentrated liquid L‐lysine monohydrochloride and L‐lysine monohydrochloride produced by Escherichia coli (FERM BP‐10941) for all animal species, based on three dossiers submitted by Ajinomoto Eurolysine SAS [PDF]

EFSA Journal, 2013
Concentrated liquid L-lysine (base), concentrated liquid L-lysine monohydrochloride (HCl) and L-lysine HCl technically pure are produced by fermentation with a genetically modified Escherichia coli (FERM BP-10941). Neither the production strain nor its recombinant DNA was detected in any of the final products. The final products do not raise any safety

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 23: Suitability of taxonomic units notified to EFSA until September 2025

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety of microorganisms intentionally added to the food and feed chain.
