Microbiology and Molecular Biology Reviews, 2007 SUMMARYColicins are proteins produced by and toxic for some strains ofEscherichia coli. They are produced by strains ofE. colicarrying a colicinogenic plasmid that bears the genetic determinants for colicin synthesis, immunity, and release. Insights gained into each fundamental aspect of their biology are presented: their synthesis, which is under SOS ...

Phenotypic and Genotypic Profile of Enterobacteriaceae Isolated at a Teaching Hospital in Ghana. [PDF]
MicrobiologyopenThis study identified a significant prevalence of antimicrobial resistance determinants within Enterobacteriaceae isolates, with particular emphasis on those producing extended‐spectrum β‐lactamases (ESBL). These isolates harbored diverse antibiotic resistance genes (ARGs), plasmid replicons, and virulence factors (VFs), highlighting the imperative for

Mechanism of export of colicin E1 and colicin E3 [PDF]
Journal of Bacteriology, 1979 The mechanism of export of colicins E1 and E3 was examined. Neither colicin E1, colicin E3, Nor colicin E3 immunity protein appears to be synthesized as a precursor protein with an amino-terminal extension. Instead, the colicins, as well as the colicin E3 immunity protein, appear to leave the cells where they are made, long after their synthesis, by a ...

Mutational analysis of Cvab, an ABC transporter involved in the secretion of active colicin V. [PDF]
PLoS ONE, 2012 CvaB is the central membrane transporter of the colicin V secretion system that belongs to an ATP-binding cassette superfamily. Previous data showed that the N-terminal and C-terminal domains of CvaB are essential for the function of CvaB.

Sequencing Analysis of cvaC Gene in Acinetobacter Baumannii That Isolates from Different Infections [PDF]
Journal of Applied Sciences and Nanotechnology, 2021 Acinetobacter baumannii is one of the opportunistic nurses responsible for many acquired infections in hospitals due to its ability to resist many antibiotics. This is one of the problems facing hospitals in the world. Identification of the cvaC gene and

Screening and Molecular Dynamic Simulations of Colicin Produced by Commensals Escherichia coli Isolated from Animals [PDF]
Basrah Journal of Veterinary ResearchE. coli strains isolated from animal feces were subjected to detection of colicin production. The produced colicin was prepared as a disc to serve as an inhibitor for other types of bacteria on Mueller-Hinton agar.

Optimizing Cell-Free Protein Synthesis for Increased Yield and Activity of Colicins
Methods and Protocols, 2019 Colicins are antimicrobial proteins produced by Escherichia coli that hold great promise as viable complements or alternatives to antibiotics. Cell-free protein synthesis (CFPS) is a useful production platform for toxic proteins because it eliminates the
