|---|
| This is an open or another expanded state of the mechanosensor (Bass et al. 2002, Akitake et al. 2005). MscS is inserted in the "monotopic" mode (it does not transverse the bilayer), due to the missing (disordered) N-terminal segment of alpha-helix in each of seven subunits. Key voltage-sensitive arginines remain outside of the calculated hydrophobic slab, in the lipid head group region. |
