Pore-forming activity-caged macrolittin 70
WebThis mechanism of pore formation is widespread and biologically significant. Pore-forming proteins (PFPs) interact with lipid bilayers to compromise membrane integrity. Many PFPs function by inserting a ring of oligomerized subunits into the bilayer to form a protein-lined hydrophilic channel. However, mounting evidence suggests that PFPs can ...
