FunctionHemolysin (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. RelevanceHL acts as a virulence factor in the pathogenesis of invasive infections[2]. 3D Printed Physical Model of HemolysinShown below is a 3D printed physical model of Hemolysin. The model is shown in alpha carbon backbone format with each chain colored uniquely.
