GDP-glucose: ceramide transferase into different thicknesses of lipid membranes
and the enzyme activities of those cases. Different phosphatidylcholines with saturated fatty acyl chains from 15 carbons to 18 carbons are used for different thicknesses of lipid bilayer membranes. And the maximum activity obtained when the
enzyme is reconstructed in dimyristoylphosphatidylcholine (12 carbons fatty acid),
which means the enzyme takes optimum configuration in interaction with
dimyristoylphosphatidylcholine.
