Function

Hemolysin (HL) is exotoxin from bacteria which causes lysis of red blood cells^[1]. α-hemolysin from the bacterium Clostridium are called alpha-toxin. They are zinc metalloenzymes which bind 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].
