Usage

Description

Alpha-Hemolysin, also known as α-hemolysin, is a pore-forming cytotoxin and an extracellular protein secreted by most strains of pathogenic Staphylococcus aureus. It is secreted as a water-soluble monomer and is a small β-barrel protein.
Used in Microbiology Research:
Alpha-Hemolysin is used as a research tool for studying the efflux pump and haemolysin activity of Escherichia coli of dairy origin. It helps in understanding the bacterial adaptation to benzalkonium chloride and the effect of ciprofloxacin on biofilm formation.

Biochem/physiol Actions

α-Hemolysin is selectively hemolytic and the monomeric form binds to a membrane and specific receptors are not required for binding. Upon binding to biological membranes and/or artificial membranes, self-oligomerization occurs, resulting in ring structures (hexameric aggregates) believed to represent transmembrane pores, which are permeable to ions and small metabolites. It has a marked preference for rabbit red blood cells. α-hemolysin stimulates cellular phospholipases and induces a Ca2+?influx. It leads to membrane disruption of the endothelial barrier and leakage of cytoplasmic components and osmotic lysis of the cells. α-hemolysin is implicated in the pathogenesis of sepsis.
