Spatial localization of PtdInsP2 in phase-separated giant unilamellar vesicles with a fluorescent PLC-delta 1 PH domain
, Methods Mol.Biol., Vol: 462, Pages: 135-144This chapter describes a method for the preparation of giant unilamellar vesicles containing phosphatidylinositol 4,5-bisphosphate that are larger than 20 microm in size. The phospholipids composition of the vesicular membrane is such that fluid lamellar and liquid-ordered or gel phases are formed and separate within the confines of one vesicle. It outlines the preparation of a protein fluorescent label, pleckstrin homology domain from phospholipase C-delta 1, that binds specifically to phosphatidylinositol 4,5-bisphosphate. Using fluorescence microscopy, the presence and spatial position of this phosphorylated phosphatidylinositol lipid on the lipid membrane have been located with the pleckstrin homology domain. We show that phosphatidylinositol 4,5-bisphosphate and the phospholipase C-delta 1 pleckstrin homology domain are located to the fluid phase of the vesicle membrane. This approach can therefore show how membrane physical properties can affect enzyme binding to phosphatidylinositol 4,5-bisphosphate and thus further the understanding of important membrane processes such as endocytosis

X-ray diffraction measurement of the monolayer spontaneous curvature of dioleoylphosphatidylglycerol
, CHEMISTRY AND PHYSICS OF LIPIDS, Vol: 154, Pages: {64-67}-{64-67}, ISSN: 0009-3084Phosphatidylglycerol (PG) is an anionic lipid commonly found in large proportions in the cell membranes of bacteria and plants and, to a lesser extent, in animal cells. PG plays an important role in the regulation and determination of the elastic properties of the membrane. Using small angle X-ray scattering experiments, we obtain that the monolayer spontaneous curvature of dioleoylphosphatidylglycerol (DOPG) is -1/150 +/- 0.021 nm(-1) when measured in 150mM NaCl. When the experiments are carried out in 150 mM NaCl and 20 mM MgCl2, the value obtained for the monolayer spontaneous curvature is -1/8.7 +/- 0.037 nm(-1). These values are of importance in modelling the effects of curvature elastic stress in membrane lipid homeostasis in the bacterium Acholeplasma laidlawii [Alley, S.H., Barahona, M., Ces, O., Templer, R.H., in press. Biophysical regulation of lipid biosynthesis in the plasma membrane. Biophys. J.] and indicate that divalent cations can play a significant role in altering curvature elastic stress.

Biophysical regulation of lipid biosynthesis in the plasma membrane
, BIOPHYSICAL JOURNAL, Vol: 94, Pages: {2938-2954}-{2938-2954}, ISSN: 0006-3495We present a cellular model of lipid biosynthesis in the plasma membrane that couples biochemical and biophysical features of the enzymatic network of the cell-wall-less Mycoplasma Acholeplasma laidlawii. In particular, we formulate how the stored elastic energy of the lipid bilayer can modify the activity of curvature-sensitive enzymes through the binding of amphipathic a-helices. As the binding depends on lipid composition, this results in a biophysical feedback mechanism for the regulation of the stored elastic energy. The model shows that the presence of feedback increases the robustness of the steady state of the system, in the sense that biologically inviable nonbilayer states are less likely. We also show that the biophysical and biochemical features of the network have implications as to which enzymes are most efficient at implementing the regulation. The network imposes restrictions on the steady-state balance between bilayer and nonbilayer lipids and on the concentrations of particular lipids. Finally, we consider the influence of the length of the amphipathic a-helix on the efficacy of the feedback and propose experimental measurements and extensions of the modeling framework.
