Colicins are plasmid-encoded narrow spectrum antibiotics that are synthesized by strains of Escherichia coli and govern intraspecies competition. In a previous report, we demonstrated that the global transcriptional factor IscR, co dependently with the ...

Colicins of the Escherichia coli uropathogenic strain collection
110 uropathogenic Escherichia coli (UPEC) strains were screened for colicin production and 42 (38%) of the tested UPEC strains were found to be colicinogenic.

Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

Colicins and Salmocins – New Classes of Plant-Made Non-antibiotic Food Antibacterials
Recently, several plant-made recombinant proteins received favorable regulatory review as food antibacterials in the United States through the Generally Recognized As Safe (GRAS) regulatory procedure, and applications for others are pending.

The Subgingival Host–Microbial Landscape in Mothers With Periodontitis and Their At‐Risk Offspring
ABSTRACT Aim To evaluate the subgingival proteome and microbiome of mothers with periodontitis and their offspring, thereby assessing signatures of periodontal diseases. Methods Forty participants in four groups were included: mothers with periodontitis and their offspring, as well as periodontally healthy mothers and their offspring.

The LPS core is critical for virulence in Pectobacterium carotovorum, as its truncation disrupts outer membrane protein assembly, reducing protease secretion, motility, and soft rot symptoms. ABSTRACT Lipopolysaccharide (LPS) is a critical component of the bacterial outer membrane, which serves as a permeability barrier and site for sensing ...

Mode of Action of Colicin A [PDF]
Colicin A acting on sensitive cells of Escherichia coli inhibits a number of energy-requiring cellular functions. It appears to act similarly to colicins E1 and K.

Deciphering the Role of Colicins during Colonization of the Mammalian Gut by Commensal E. coli
Colicins are specific and potent toxins produced by Enterobacteriaceae that result in the rapid elimination of sensitive cells. Colicin production is commonly found throughout microbial populations, suggesting its potential importance for bacterial ...

Klebsiella pneumoniae is a Gram‐negative, facultatively anaerobic member of the Enterobacteriaceae that functions both as a gut commensal and a major opportunistic pathogen implicated in severe hospital and community‐acquired infections. The rapid global expansion of antimicrobial‐resistant K.

The pore-forming colicins N and A require the porin, OmpF, in order to translocate across the outer membrane of Escherichia coli. We investigated the hypothesis that in vivo, colicins N and A may traverse the outer membrane through the OmpF channel.
