Comparative genomics of Shiga toxin encoding bacteriophages [PDF]

, 2012
Background Stx bacteriophages are responsible for driving the dissemination of Stx toxin genes (stx) across their bacterial host range. Lysogens carrying Stx phages can cause severe, lifethreatening disease and Stx toxin is an integral virulence factor.

Genetic distribution, characterization, and function of Escherichia coli type III secretion system 2 (ETT2)

iScience
Summary: Many Gram-negative bacteria use type Ⅲ secretion system (T3SS) to inject effector proteins and subvert host signaling pathways, facilitating the growth, survival, and virulence.

Genomic island-encoded regulatory proteins in enterohemorrhagic Escherichia coli O157:H7

Virulence
Enterohemorrhagic Escherichia coli (EHEC) is an important zoonotic pathogen that is a major cause of foodborne diseases in most developed and developing countries and can cause uncomplicated diarrhoea, haemorrhagic colitis, and haemolytic uraemic ...

Proteomic analysis of Escherichia coli detergent-resistant membranes (DRM).

PLoS ONE, 2019
Membrane microdomains or lipid rafts compartmentalize cellular processes by laterally organizing membrane components. Such sub-membrane structures were mainly described in eukaryotic cells, but, recently, also in bacteria.

Label-free quantitative proteomic analysis of the inhibition effect of Lactobacillus rhamnosus GG on Escherichia coli biofilm formation in co-culture

Proteome Science, 2021
Background Escherichia coli (E. coli) is the principal pathogen that causes biofilm formation. Biofilms are associated with infectious diseases and antibiotic resistance.

The yhiM gene codes for an inner membrane protein involved in GABA export in Escherichia coli [PDF]

, 2017
In order to survive the exposure to acid pH, Escherichia coli activates molecular circuits leading from acid tolerance to extreme acid resistance (AR). The activation of the different circuits involves several global and specific regulators affecting the

Comparison of bacterial intracellular and secreted proteins produced in milk versus medium for Escherichia coli by proteomic analysis

Journal of Dairy Science
: The growth and reproduction of microorganisms are dependent on nutrient supply. Here, milk and Luria-Bertani (LB) media were used as nutrition sources for Escherichia coli, and the changes in bacterial and secretory proteins at 3 time points (3, 9, and

Remarkable diversity in the enzymes catalyzing the last step in synthesis of the pimelate moiety of biotin. [PDF]

PLoS ONE, 2012
Biotin synthesis in Escherichia coli requires the functions of the bioH and bioC genes to synthesize the precursor pimelate moiety by use of a modified fatty acid biosynthesis pathway.
