Energies and Dynamics of Ca2+/MG2+-Mediated Vesicle Docking, Measured using Single Particle Tracking

Abstract

sub-diffusive (t<20ps) and super-diffusive (0.1ns<t<1ns) regimes. Apparently the latter has not been reported before, and it appears to be correlated with the out-of-plane fluctuations of the lipid molecules. The anomalous super-and sub-diffusive regimes lead to a self-intermediate scattering function with compressed-and stretched exponential relaxation, respectively. In principle, these predictions should be testable using neutron scattering (NS) experiments. In practice, however, the NS signal will most likely be totally dominated by the contribution from the abundant ordinary bulk water.
