The influence of non-inhibitory concentrations of purified pyocin S2 on Pseudomonas aeruginosa isolates
… beneficial and antagonistic interactions. S-type pyocins are bacteriocin proteins produced by P. aeruginosa that can inhibit closely related strains. Previously, we observed a P. aeruginosa isolate using S-type pyocins to decrease the virulence of other isolates in a Drosophila melanogaster model. …

The Noncontractile Phage Tail-like Bacterial Killing Nanomachines – Characterizing the Specificity Determinants of the F-Pyocins of Pseudomonas aeruginosa
… phage tail-like entities called F-pyocins. F-pyocins are high molecular weight bacteriocins resembling non-contractile bacteriophage tails such as E coli phage lambda of the Siphoviridae family. They are produced by many Pseudomonas aeruginosa strains and possess bactericidal …

The effect of antibiotics on Pseudomonas aeruginosa biofilm production
… Extraction of Colicin V from E. coli and Pyocin S2 from P. aeruginosa was unsuccessful. Nanodrop analysis determined that there was minimal protein in each sample (concentrations between 0.196-3.118mg/mL). In the future, bacteriocin extractions should be successfully performed, and …

Integration of Structural Methods to Characterize the Dynamics of Macromolecular Complexes
… Following this, we describe the mechanism of pyocin contraction using a combination of purpose-made computational modelling, electron microscopy and biophysical assays. Together, we characterize the relevant energetics and forces generated throughout the contraction process. Moreover, we …

Controlling Pseudomonas aeruginosa Persister Cells by Human Granulocyte Macrophage Colony-Stimulating Factor
… revealed that GM-CSF induced flagella and pyocin associated genes in persister cells of P. aeruginosa PAO1, while the same genes in normal cells did not show significant change. Using co-immunoprecipitation (co-IP) and cross-linking, GM-CSF was found to interact with the protein FliC …

Electrochemical Control of Bacterial Persister Cells
… of genes involved in antibiotic resistance, pyocin-related functions, and SOS response. Comparative transmission electron microscopy (TEM) studies of the stationary phase <em>P. aeruginosa</em> PAO1 cells confirmed that DC treatments resulted in the compartmentalization of intracellular …
