Figure 9
Schematic model of how GTP hydrolysis is coupled to membrane association. The arrangement of the septin octameric complex is shown, in which the SEPT9 homodimeric NC interface, at the centre of the rod, is shown closed (left) and open (right). The corresponding positions for α0, with its positive charge, are exposed and hidden, respectively. The former is expected to favour membrane association.
