β-hemolysin (hlb; Q2FWP1) 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. See more 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 importance … See more One way hemolysin lyses erythrocytes is by forming pores in phospholipid bilayers. Other hemolysins lyse erythrocytes by hydrolyzing the phospholipids in the bilayer. See more 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. Since free iron may generate damaging free radicals, free iron is typically maintained at low … See more Medicine Thermostable Direct Hemolysin (TDH; InterPro: IPR005015) produced by Vibrio parahaemolyticus is now being studied in the field of See more Many bacteria produce hemolysins that can be detected in the laboratory. It is now believed that many clinically relevant fungi also produce hemolysins. Hemolysins can be identified by their ability to lyse red blood cells in vitro. Not only are the … See more The structure of several hemolysins has been solved by X-ray crystallography in the soluble and pore-forming conformations. For example, α-hemolysin of Staphylococcus aureus forms a homo-heptameric β-barrel in biological membranes. The See more As hemolysins are produced by pathogenic organisms, the main treatment is the intake of antibiotics specific to the pathogen that have caused the infection. Moreover, some hemolysins may be neutralized by the action of anti-hemolysin antibodies, … See more WebJan 1, 2024 · Definition Test zum Nachweis von Donath-Landsteiner-Antikörpern.
