New Players in the Toxin Field: Polymorphic Toxin Systems in Bacteria

mBio, 2015
Bacteria have evolved numerous strategies to increase their competitiveness and fight against each other. Indeed, a large arsenal of antibacterial weapons is available in order to inhibit the proliferation of competitor cells.

Molecular Mechanism of Action of Pore-Forming Colicins and of their Immunity Proteins

, 1992
International audiencePore-forming colicins constitute a large family of homologous bacteriocins that are of interest for a variety of problems related to membranes.

Colicins exploit native disorder to gain cell entry: a hitchhiker's guide to translocation.

, 2008
The translocation of protein toxins into a cell relies on a myriad of protein-protein interactions. One such group of toxins are enzymatic E colicins, protein antibiotics produced by Escherichia coli in times of stress.

Molecular Identification of the colicin types in Escherichia coli in the Yasuj city

Armaghane Danesh Bimonthly Journal, 2014
Background & aim: colicins are a group of bacteriocins produce by Escherichia coli and act against pathogenic bacteria Escherichia coli. Today, the use of colicinogenic strains as probiotic microorganisms and replace them instead of the combination of ...

Determination of the structure of pore-forming colicins [PDF]

, 2017
6 Abstract This master's thesis provides study of individual helixes from C-terminal pore-forming domain (CTD) of colicin U and their behavior in lipid bilayer on atomic level. For this purpose the all-atom molecular simulation method was used. Later the

Antibacterial Activity of the Peptide Microcin J25 Produced by Escherichia coli

Medical Laboratory Journal, 2022
Background and objectives: Bacteriocins are generally active antimicrobial peptides effective against bacteria closely related to the producer. Escherichia coli produce two bacteriocins: colicins and microcins.

Colicins U and Y inhibit growth of Escherichia coli strains via recognition of conserved OmpA extracellular loop 1

, 2017
Interactions of colicins U and Y with the OmpA (Outer membrane protein A) receptor molecule were studied using site-directed mutagenesis and colicin binding assay.

Protein import into Escherichia coli: colicins A and E1 interact with a component of their translocation system.

, 1991
International audienceColicins are antibiotic proteins that kill sensitive Escherichia coli cells. Their mode of action involves three steps: binding to specific receptors located in the outer membrane, translocation across this membrane, and action on ...
