Polarized neutron reflectometry on cell-free-expressed MscL in tethered lipid bilayers shows the fitted C-terminal protrusion drops from about 46 to 38 Å after adding pexiganan, consistent with gating toward the open state.
Values for the lipid head and tail group volumes were taken from the RefNX database[7–9] The SLDs of the silicon and silicon oxide were fixed at literat ure values

Neutron Reflectometry Reveals Conformational Changes in a Mechanosensitive Protein Induced by an Antimicrobial Peptide in Tethered Lipid Bilayers
Polarized neutron reflectometry on cell-free-expressed MscL in tethered lipid bilayers shows the fitted C-terminal protrusion drops from about 46 to 38 Å after adding pexiganan, consistent with gating toward the open state.
