Artifical membrane systems are being used increasingly to study the
function and role of plant membrane proteins, particularly solute
transporters which catalyse counter-exchange of metabolites. Performing
such studies requires (i) solubilization of the protein with a suitable
surfactant, (ii) functional reconstitution of the protein in a well
characterized liposome system. Much of the technology has been derived from
studies on non-plant systems and there are many pitfalls of which to be
wary before applying it to a new protein. This short review outlines the
key parameters which should be considered when attempting the study of
plant membrane proteins in artificial lipid bilayers, including types of
surfactants, lipid composition of vesicles, membrane permeability, and
protein orientation.Keywords: Membrane protein
reconstitution, liposomes, surfactants, membrane solubilization
