Function
Alpha-hemolysin [1] is a toxin secreted by Staphylococcus aureus as a pore-forming heptamer that binds to eukaryotic cell membranes. This protein belongs to a family of bacterial exotoxins[2]. The primary function of alpha-hemolysin is cytolytic, and is achieved by the release of cytosolic K+ ions from the through the hydrophilic, transmembrane portion of the beta-barrel pore[3].
