Chemical Structure
Biological Activity: Streptolysin O is a cholesterol-targeting, thiol-activated pore-forming toxin. Streptolysin O binds to cholesterol via its C-terminal domain 4, oligomerizes to form arc-shaped or ring-shaped structures, inserts amphipathic helices into the lipid bilayer, and forms transmembrane β-barrel pores, resulting in cell permeabilization. Streptolysin O enables controllable cell membrane permeabilization, fluorescent probe delivery, and exogenous molecule uptake[1][2][3][4][5].
