Native Streptolysin O from Escherichia coli


Cat No.
NATE-1161
Description
Streptolysin O possesses a single polypeptide chain with a molecular weight of f62 kDa. Streptolysin O binds to membrane cholesterol and oligomerizes to create a ring structure that consists of 45 to 50 units. The ring structure inserts into the membrane to make a large pore (25 to 30 nm), which DNA, RNA, peptides and proteins may pass. It is thiol-activated. It is inhibited by allicin, an active component of garlic.

Product Overview
Streptolysin-O is one of several toxic immunogenic exoenzymes produced by most strains of group A and many strains of groups C and G, β-hemolytic streptococci. The O in the name stands for oxygenlabile; the other related toxin being oxygen-stable streptolysin-S. The main function of streptolysin O is to cause hemolysis (the breaking open of red blood cells) in particular, beta-hemolysis.
