Hemolysin (HL) is exotoxin from bacteria which causes lysis of red blood cells. 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.
