Hemolysin secretion
β-hemolysin (hlb; ) is a Phospholipase C toxin secreted by S. aureus. Upon investigating sheep erythrocytes, its toxic mechanism was discovered to be the hydrolysis of a specific membrane lipid, sphingomyelin, which accounts for 50% of the cell’s membrane. Meer weergeven Hemolysins or haemolysins are lipids and proteins that cause lysis of red blood cells by disrupting the cell membrane. Although the lytic activity of some microbe-derived hemolysins on red blood cells may be of great … Meer weergeven One way hemolysin lyses erythrocytes is by forming pores in phospholipid bilayers. Other hemolysins lyse erythrocytes by hydrolyzing … Meer weergeven Hemolysins are thought to be responsible for many events in host cells. For example, iron may be a limiting factor in the growth of various pathogenic bacteria.
