Autoinduced synthesis of colicin E2

Molecular and General Genetics MGG, 1983
Escherichia coli K-12 cells carrying the high copy number plasmid ColE2-P9 and a sfiA-lacZ gene fusion exhibit abnormally high levels of SOS-regulated phi sfiA-lacZ expression. Increased sfiA-lacZ expression is caused by the action of colicin E2, which is a DNase, rather than by the presence of multiple copies of a binding site for LexA protein, the ...

Novel synthetic analogs of the Pseudomonas autoinducer

Bioorganic & Medicinal Chemistry Letters, 1999
Release of virulence factors in Pseudomonas aeruginosa is regulated by two N-acylhomoserine lactones, PAI-1 and PAI-2, that activate the respective transcription factors LasR and RhlR. With the goal of developing novel therapeutic agents, we synthesized constrained analogs of PAI-1 and evaluated them in P. aeruginosa.

Autoinducing peptide-based quorum signaling systems in Clostridioides difficile

Current Opinion in Microbiology, 2022
The autoinducing peptide-based Agr system in Clostridioides difficile is involved in virulence factor expression, motility, and sporulation. This review highlights several of the recent discoveries regarding C. difficile Agr. Typical Agr systems rely on the combined activities of four proteins involved in peptide expression, peptide processing, peptide

Bacterial Interference Caused by Autoinducing Peptide Variants

Science, 1997
The synthesis of virulence factors and other extracellular proteins by Staphylococcus aureus is globally controlled by the agr locus, which encodes a two-component signaling pathway whose activating ligand is an agr -encoded autoinducing peptide.
