streptolysin

The main function of streptolysin O is to cause hemolysis (the breaking open of red blood cells) in particular, beta-hemolysis.

The regulation of gene expression of hemolysins (such as streptolysin S) is a system repressed in the presence of iron.

One of the most widely recognized putative streptococcal virulence factors is the oxygen-stable hemolysin, streptolysin S (SLS).

The protein analyzer showed the expected toxins and enzymes being made by the bacteria: Streptolysin O, Streptolysin S, erythrogenic toxin, streptokinase, streptodornase, proteinase.

There are two types of streptolysin: Streptolysin O (SLO) and streptolysin S (SLS).

Types include Streptolysin O (SLO), which is oxygen-labile, and Streptolysin S (SLS), which is oxygen-stable.
