Membrane-dependent conformational changes initiate cholesterol-dependent cytolysin oligomerization and intersubunit beta-strand alignment.

Abstract excerpt

Cholesterol-dependent cytolysins are bacterial protein toxins that bind to cholesterol-containing membranes, form oligomeric complexes and insert into the bilayer to create large aqueous pores. Membrane-dependent structural rearrangements required to initiate the oligomerization of perfringolysin O monomers have been identified, as have the monomer-monomer interaction surfaces, using site-specific mutagenesis,...
