Use of black soldier fly (Hermetia illucens) prepupae amino acids as anti Aeromonas hydrophila enterotoxin in vivo [PDF]
Iraqi Journal of Veterinary Sciences, 2023 Aeromonas hydrophila is an opportunistic freshwater. These bacteria cause gastroenteritis and septicemia in animals and humans. Hemolysin and aerolysin, are important in the pathogenesis of A. hydrophila.

The hemolysin A secretion system is a multi-engine pump containing three ABC transporters.
Cell, 2022 Type 1 secretion systems (T1SSs) are widespread in pathogenic Gram-negative bacteria, extruding protein substrates following synthesis of the entire polypeptide.

Erythrocyte-camouflaged biosensor for α-hemolysin detection.
Biosensors & bioelectronics, 2021 Without appropriate treatment, Staphylococcus aureus (S. aureus) infection can cause life-threatening diseases (e.g., meningitis, pneumonia, bacteremia, and sepsis).

RNase A does not translocate the alpha-hemolysin pore. [PDF]
PLoS ONE, 2014 The application of nanopore sensing utilizing the α-hemolysin pore to probe proteins at single-molecule resolution has expanded rapidly. In some studies protein translocation through the α-hemolysin has been reported. However, there is no direct evidence,

Unidirectional Single-File Transport of Full-Length Proteins Through a Nanopore
bioRxiv, 2021 Full-length, unfolded proteins are slowly translocated through nanopores without enzymes and fingerprinted. The electrical current blockade of a peptide or protein threading through a nanopore can be used as a fingerprint of the molecule in biosensor ...

IL-21 Enhances the Immune Protection Induced by the Vibrio vulnificus Hemolysin A Protein [PDF]
Inflammation, 2021 Abstract We previously reported that the Vibrio vulnificus hemolysin A (VvhA) protein elicited good immune protection and could effectively control V. vulnificus infection in mice. However, its molecular mechanism remains unknown. In this study, we found that IL-21 enhances immune protection by inducing a Tfh-cell and germinal center (GC) B ...

Redirecting Pore Assembly of Staphylococcal α-Hemolysin by Protein Engineering [PDF]
ACS Central Science, 2019 α-Hemolysin (αHL), a β-barrel pore-forming toxin (βPFT), is secreted as a water-soluble monomer by Staphylococcus aureus. Upon binding to receptors on target cell membranes, αHL assembles to form heptameric membrane-spanning pores. We have previously engineered αHL to create a protease-activatable toxin that is activated by site-specific proteolysis ...

Antibiotics shaping bacterial genome: deletion of an IS91 flanked virulence determinant upon exposure to subinhibitory antibiotic concentrations. [PDF]
PLoS ONE, 2011 The nucleoid-associated proteins Hha and YdgT repress the expression of the toxin α-hemolysin. An Escherichia coli mutant lacking these proteins overexpresses the toxin α-hemolysin encoded in the multicopy recombinant plasmid pANN202-312R.

The fusion protein of peste des petits ruminants virus is a hemolysin [PDF]
Archives of Virology, 1999 The fusion glycoprotein (F protein) of paramyxoviruses plays a vital role in virus-induced cytopathology. To explore the role of the F protein in peste des petits ruminants virus (PPRV)-induced cytopathology, the F protein of PPRV was purified by immunoaffinity chromatography.
