Hemolysin

spinqualitylabelsall models α-hemolysin heptamer (PDB code 7ahl). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function 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. For toxins in Proteopdia see Toxins. Relevance HL acts as a virulence factor in the pathogenesis of invasive infections.
