Colicins, a class of antimicrobial compounds produced by bacteria, are thought to be important mediators of intra- and interspecific interactions, and are a significant factor in maintaining microbial diversity. Colicins B and M are among the most common colicins produced by Escherichia coli, and are usually encoded adjacently on the same plasmid. In this study, the characterization of a collection of E. coli isolated from Australian vertebrates revealed that a significant fraction of colicin BM strains lack an intact colicin B activity gene. The colicin B and M gene region was sequenced in 60 strains and it was found (with one exception) that all plasmids lacking an intact colicin B activity gene have an identical colicin gene structure, possessing a complete colicin B immunity gene and a 130 bp remnant of the B activity gene. A phylogenetic analysis of the colicin M and B operons and characterization of the plasmids suggested that ColBM plasmids with a truncated B activity gene have evolved on at

A Tn5-based transposon bearing the kil gene (killing protein), mediating controlled export of periplasmic proteins into the culture medium, was constructed (Tn5-KIL3). This transposon contained the kil gene of the ColE1 plasmid under the growth-phase-dependent promoter of the fic gene (filamentation induced by cAMP) of Escherichia coli, an interposon located upstream of kil, a kanamycin/neomycin-resistance gene, a multiple cloning site and the mob site. The transposition of Tn5-KIL3 to Acetobacter methanolicus showed a moderate transposition frequency (10(-5)-10(-6)). By insertion of a Bacillus hybrid beta-glucanase (bgl) as a model protein into the transposon (Tn5-LF3) it was shown that the secretion function as well as the gene of the target protein had been transferred to and stably integrated into the chromosome of A, methanolicus, and that the transposition of Tn5-LF3 was non-specific. beta-Glucanase was highly overexpressed and secreted into the medium during stationary phase.

Plasmid ColIb-P9 (Incll) encodes mechanisms which allow it to avoid destruction by type I and type II restriction enzymes during transfer by conjugation between strains of Escherichia coli. A genetic system was developed to analyse these mechanisms. The system relied on measuring Collb-mediated rescue of the restriction-sensitive plasmid R751 (IncPp) from destruction by EcoKI (type I) and EcoRI (type II). One Collb mechanism was known to involve a plasmid-encoded antirestriction gene known as ardA, the product of which is active against type I enzymes. Tests for alleviation of EcoKI restriction of R751, showed strong protection by a co-transferring Collb (Ard+) plasmid, slight protection when Collb was resident in the recipient and no effect when Collb was immobilised in the donor by removal of its nic site. Hence, expression of ardA is activated in the recipient cell following transfer no detectable transfer of the ArdA protein occurs from the donor to the recipient. The ardA gene is found in ...

This work has studied colicin translocation by using a periplasmic protection assay combined with an in vivo lux-reporter assay and a potassium release assay. Expressing the translocation domain of colicin A in the periplasm and challenging the cells with external colicins showed that the translocation of group A colicins is inhibited as it requires an interaction with the Tol system. Surprisingly, the TolA protein was found to play the major role during the translocation of both ColA and the endonuclease colicin E9 even though the latter colicin has no direct interaction with the TolA protein. This study also suggests that the interaction with TolB is important for both colicins A and E9. Moreover, a series of ColA constructs with a truncated T domain were made by site directed mutagenesis to define the important residues of the TolA and TolB boxes for their interaction with Tol proteins. The results showed that tyrosine 58 residue of the TolA box of colicin A is essential for TolA binding, ...
pRV500 is, to our knowledge, the first plasmid of L. sakei to be entirely sequenced. Careful sequence analysis showed that pRV500 belongs to the pUCL287 family, itself related to class A theta-type plasmids of the pUCL22 and pSC101 families. Experimental evidence of the theta replication mode was obtained for pUCL287 itself (2). Although the minimum length of the pRV500 oriA region remains to be determined, it is likely to involve the same two kinds of DNA repeats as other pUCL287-type plasmids. The involvement of repetitive sequences of 22 bp (iterons) as a target for binding of the Rep protein was demonstrated for pSBO1 (40), and the upstream 11-bp repeated sequences were observed to be essential for pUCL287 replication (3).. Like other plasmids (14, 49), pRV500 appears to be a composite structure containing DNA segments from different sources. Some ORFs are shared by plasmids from both subfamilies pUCL22 and pUCL287; this applies to orf6 in pRV500 and ORFs of unknown function around the gene ...
Colicin E1 induces the efflux of carboxyfluorescein and calcein from liposomes whose phospholipid composition is similar to that of Escherichia coli. This colicin action takes place at protein-to-liposome ratios and within pH ranges that are physiologically meaningful. Colicin-induced permeability of carboxyfluorescein is not limited to the initial phase of colicin membrane interaction but is sustained thereafter. Colicin E1 requires negatively charged phospholipids in the liposomal membrane in order to bind and induce efflux.

The Role of Bacteriocins in Mediating Bacterial Competitive Interactions. Explaining the coexistence of competing species is a major challenge in community ecology. In bacterial systems, competition is often driven by the production of bacteriocins, which are narrow-spectrum proteinaceous toxins that serve to kill closely related species, providing the producer better access to limited resources. Bacteriocin producers have been shown to competitively exclude sensitive, nonproducing strains. However, the dynamics between bacteriocin producers, each lethal to its competitor, are largely unknown. In this study, we used in vitro, in vivo and in silico models to study competitive interactions between bacteriocin producers. Two Escherichia coli strains were generated, each carrying a DNA-degrading bacteriocin (colicins E2 and E7). Using reporter-gene assays, we showed that each DNase bacteriocin is not only lethal to its opponent but, at lower doses, can also induce the expression of its opponents ...
Individual bacterial cells may contain several different types of plasmids and in some cases more than 10 at a time. Plasmids are generally isolated from the bacterial cells in the supercoiled configuration. So far, thousands of different types of plasmids have been isolated. More than 300 different types of naturally occurring plasmids have been isolated from E.coli alone. Though, plasmids are not considered as part of the cells genome, when a bacterial cell divides each daughter cells receives a copy of each plasmid. Plasmids can also be transferred from one bacterial cell to another by the process called conjugation. Plasmids that govern their own transfer by conjugation are called conjugative plasmids but not all plasmids are conjugative.. ...

Binding of enzymatic E colicins to the vitamin B12 receptor, BtuB, is the first stage in a cascade of events that culminate in the translocation of the cytotoxic nuclease into the Escherichia coli cytoplasm and release of its tightly bound immunity protein. A dogma of colicin biology is that the toxin coiled-coil connecting its functional domains must unfold or unfurl to span the periplasm, with recent reports claiming this reaction is initiated by receptor binding. We report isothermal titration calorimetry data of BtuB binding the endonuclease toxin ColE9 and a disulfide form (ColE9S-S) where unfolding of the coiled-coil is prevented and, as a consequence, the toxin is biologically inactive. Contrary to expectation, the thermodynamics of receptor binding, characterized by large negative values for TDeltaS, are identical for the two colicins, arguing against any form of BtuB-induced unfolding. We go on to delineate key features of the colicin translocon that assembles at the cell surface after BtuB
