Structure and sequence analyses of Bacteroides proteins BVU_4064 and BF1687 reveal presence of two novel predominantly-beta domains, predicted to be involved in lipid and cell surface interactions. [PDF]

open access: yes, 2015
BackgroundN-terminal domains of BVU_4064 and BF1687 proteins from Bacteroides vulgatus and Bacteroides fragilis respectively are members of the Pfam family PF12985 (DUF3869).

Mechanism of Gene Regulation by a Staphylococcus aureus Toxin

open access: yesmBio, 2016
The virulence of many bacterial pathogens, including the important human pathogen Staphylococcus aureus, depends on the secretion of frequently large amounts of toxins. Toxin production involves the need for the bacteria to make physiological adjustments

Molecular Insights into the Assembly and Functional Diversification of Typhoid Toxin

open access: yesmBio, 2022
Typhoid toxin is an A2B5 protein toxin and an important virulence factor for the human-adapted bacterial pathogen Salmonella enterica serovar Typhi, the causative agent of typhoid fever. Typhoid toxin contains two enzymatic subunits, PltA and CdtB, which

The teneurin C-terminal domain possesses nuclease activity and is apoptogenic. [PDF]

open access: yes, 2018
Teneurins are type 2 transmembrane proteins expressed by developing neurons during periods of synaptogenesis and apoptosis. Neurons expressing teneurin-1 synapse with other teneurin-1-expressing neurons, and neurons expressing teneurin-2 synapse with ...

Bacterial Toxins: Friends or Foes?

open access: yesEmerging Infectious Diseases, 1999
Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes.

Gut-Derived Metabolites and Their Role in Immune Dysfunction in Chronic Kidney Disease

open access: yesToxins, 2020
Several of the uremic toxins, which are difficult to remove by dialysis, originate from the gut bacterial metabolism. This opens opportunities for novel targets trying to decrease circulating levels of these toxins and their pathophysiological effects ...

Genetic Evidence for SecY Translocon-Mediated Import of Two Contact-Dependent Growth Inhibition (CDI) Toxins

open access: yesmBio, 2021
Many bacterial species interact via direct cell-to-cell contact using CDI systems, which provide a mechanism to inject toxins that inhibit bacterial growth into one another.

The Biological Properties of Bacterial Toxins

open access: yesВестник войск РХБ защиты
Knowledge of the biological properties of bacterial toxins is constantly being updated. Over the past two decades, the research interest has shifted from natural toxins to their genetically modified derivatives.
