Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, Volume 600, Issue 20, Page 2981-3008, October 2026.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

The LuxR receptor: the sites of interaction with quorum-sensing signals and inhibitors [PDF]

Microbiology, 2005
The function of LuxR homologues as quorum sensors is mediated by the binding of N-acyl-l-homoserine lactone (AHL) signal molecules to the N-terminal receptor site of the proteins. In this study, site-directed mutagenesis was carried out of the amino acid residues comprising the receptor site of LuxR from Vibrio fischeri, and the ability of the L42A ...

Expression and Quorum Sensing Regulation of Type III Secretion System Genes of Vibrio harveyi during Infection of Gnotobiotic Brine Shrimp. [PDF]

PLoS ONE, 2015
Type III secretion systems enable pathogens to inject their virulence factors directly into the cytoplasm of the host cells. The type III secretion system of Vibrio harveyi, a major pathogen of aquatic organisms and a model species in quorum sensing ...

Transcriptomic and Functional Analyses Reveal Roles of AclR, a luxR-type Global Regular, in Regulating Motility and Virulence of Acidovorax citrulli

Molecular Plant-Microbe Interactions, 2021
LuxR-type transcriptional regulators are essential for many physiological processes in bacteria, including pathogenesis. Acidovorax citrulli is a seedborne bacterial pathogen responsible for bacterial fruit blotch, which causes great losses in melon and ...

Ankh‐Score Produces Better Sequence Alignments Than AlphaFold3

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1631-1643, October 2026.
ABSTRACT Protein sequence alignment is one of the most fundamental procedures in bioinformatics. Due to its many downstream applications, improvements to this procedure are of great importance. We consider two revolutionary concepts that emerged recently as candidates for improving the state‐of‐the‐art alignment methods: AlphaFold and protein language ...

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...

Adaptive Laboratory Evolution Rewires Pseudomonas putida for Resource‐Efficient Acetate Assimilation

Microbial Biotechnology, Volume 19, Issue 10, October 2026.
Adaptive laboratory evolution selected key mutations that improved acetate tolerance in genome‐reduced Pseudomonas putida. Multi‐omic analyses showed that adaptation increased biomass yield by reallocating resources away from costly stress‐associated programs and redirecting acetate carbon toward carbon‐conserving metabolism.
