Colicin U, a novel colicin produced by Shigella boydii [PDF]
Journal of Bacteriology, 1997 A novel colicin, designated colicin U, was found in two Shigella boydii strains of serovars 1 and 8. Colicin U was active against bacterial strains of the genera Escherichia and Shigella. Plasmid pColU (7.3 kb) of the colicinogenic strain S. boydii M592 (serovar 8) was sequenced, and three colicin genes were identified. The colicin U activity gene, cua,

Hierarchical Post-transcriptional Regulation of Colicin E2 Expression in Escherichia coli. [PDF]
PLoS Computational Biology, 2016 Post-transcriptional regulation of gene expression plays a crucial role in many bacterial pathways. In particular, the translation of mRNA can be regulated by trans-acting, small, non-coding RNAs (sRNAs) or mRNA-binding proteins, each of which has been ...

Bacteriocin Production by Escherichia coli during Biofilm Development
Foods, 2022 Escherichia coli is a highly versatile bacterium ranging from commensal to intestinal pathogen, and is an important foodborne pathogen. E. coli species are able to prosper in multispecies biofilms and secrete bacteriocins that are only toxic to species ...

Purification and Characterization of Colicin E2 and Colicin E3
Journal of Biological Chemistry, 1967 Abstract Colicin E2 and colicin E3 were purified from Escherichia coli W3110(ColE2) and W3110(ColE3), respectively, by salt extraction, ammonium sulfate precipitation, and ion exchange chromatography on diethylaminoethyl Sephadex and carboxymethyl Sephadex.

Characterization of Colicin Ia and Colicin Ib: Antigenic Homology [PDF]
Journal of Bacteriology, 1972 Immunological techniques have been employed to determine antigenic homology between colicin Ia and colicin Ib. Results of these experiments demonstrate that the two colicins are antigenically similar.

The biology of colicin M [PDF]
FEMS Microbiology Letters, 1991 This communication summarizes our present knowledge of colicin M, an unusual member of the colicin group. The gene encoding colicin M, cma, has been sequenced and the protein isolated and purified. With a deduced molecular size of 29,453 Da, colicin M is the smallest of the known colicins. The polypeptide can be divided into functional domains for cell

mBio, 2020 Colicins are toxins produced and released by Enterobacteriaceae to kill competitors in the gut. While group A colicins employ a division of labor strategy to liberate the toxin into the environment via colicin-specific lysis, group B colicin systems lack
