The influence of charged polar headgroups on the structure and stability of archaeal membranes at high pressure and temperatures
Archaeal lipid membranes are able to remain functional at high temperatures (>70°C) and high pressures (>400 bar) in part due to their unique lipids which contain ether rather than ester linkages and their branched isoprenoid hydrocarbon chains. Archaea are known to have lipids with diverse polar headgroups and that the lipid composition of the membrane varies with pressure and temperature. Here we propose to study what role the lipid polar heads play in adaption of archaea to high temperature (HT) and high hydrostatic pressure (HHP). Using neutron diffraction we can probe how membrane structural parameters change as a function of HT and HHP and compare how these parameters differ between archaeal lipids containing several common polar headgroups found in archaea.
