A Key Motif in the Cholesterol-Dependent Cytolysins Reveals a Large Family of Related Proteins

Abstract excerpt

The cholesterol-dependent cytolysins' pore-forming mechanism relies on the ability to sense the completion of the oligomeric prepore structure and initiate the insertion of the β-barrel pore from the assembled prepore structure. These studies show that a conserved motif is an important component of the sensor that triggers the prepore-to-pore transition and that it is conserved in a large family of previously...
