Definition of hemolysin
WebThe first kind of cytolytic toxin discovered have hemolytic effects on erythrocytes of certain sensitive species, such as Human. For this reason "Hemolysin" was first used to describe any MDTs. In the 1960s certain MDTs were proved to be destructive on cells other than erythrocytes, such as leukocytes. Webα-Hemolysin is a water-soluble protein that undergoes several conformational changes from the time it is released from Staphylococcus until it interacts with a plasma membrane. Initially hemolysin is a monomer, which undergoes oligomerization into a homo-oligomeric ring finally inserting into the lipid bilayer forming a pore.
