The prepore then forms complexes with the two ∼90-kD enzymatic components, lethal factor (LF) and edema factor (EF). These complexes are endocytosed and delivered to an acidic compartment . There, the ... Webhomoheptamer [32]. Both complexes bind to the α rings and promote gate opening. Some studies have been reported that reveal the involvement of 11S activators in the production of peptides for antigen presentation through MHC class I complexes. However some cells and tissues which are not involved in the immune system, do express the 11S
