Hemolysin from the bacterium Clostridium are called alpha-toxin (AT). AT is a zinc metalloenzyme and binds to the membrane in the presence of calcium. It acts as a phospholipase C. See details for α-hemolysin in Pore forming toxin, α-hemolysin. See details of hemolysin E in Molecular Playground/ClyA. For toxins in Proteopdia see Toxins. Relevance HL acts as a virulence factor in the pathogenesis of invasive infections[2].
