Voltage-dependent behaviour of dolichyl phosphate-phosphatidylcholine bilayer lipid membranes.
The current-voltage steady-state characteristics, cyclic voltammograms and capacitance-voltage steady-state relationships of bilayer lipid membranes made from dioleoylphosphatidylcholine or its mixtures with dolichyl-12 phosphate have been studied. Sustained fluctuations of the capacitance of dolichyl phosphate modified bilayers under applied voltage were observed. The results suggest that the dynamics of dolichyl phosphate molecules in membranes can be regulated by transmembrane electrical potential.
