- Kinetic and Thermodynamic Models of the Transmembrane Lipid Asymmetry
Recently, the theoretical foundations of thermodynamic modelling of the passive interleaflet redistribution of lipid molecules have been presented as well as their application to the erythrocyte plasma membrane [Heinrich et al., 1997]. One main result of the cited work was, that a positive coupling between the transport fluxes must exist to explain the experimental data of the steady-state asymmetries of the abundant lipid components phosphatidylcholine (PC), sphingomyelin (SM) and cholesterol (Ch). Furthermore, SM must have a rather high time-constant for redistribution (very slow interleaflet movement). It has been verified that simple antiport or symport kinetic mechanisms of passive protein-mediated lipid transport cannot give rise to a sufficient high coupling without speeding up the redistribution of SM [Frickenhaus and Heinrich, 1998].

- MEMBRANE ASYMMETRY AND TRANSMEMBRANE MOVEMENT OF
A remarkable feature of several biological membrane systems is that their phospholipids are asymmetrically distributed across the lipid bilayer, a phenomenon called membrane phospholipid asymmetry. Most of our knowledge on phospholipid asymmetry of lipids has come from studies on human erythrocytes. The aminophospholipids, phosphatidylethanolamine (PE) and in particular phosphatidylserine (PS) are preferentially located in the inner leaflet of the membrane bilayer, while the other major components sphingomyelin (SM) and phosphatidylcholine (PC) are more abundant in the outer leaflet. It is assumed that phospholipids are also distributed asymmetrically in the plasma membrane of most, if not all, nucleated cells.

- VIRUS-MEMBRANE FUSION - THE FUSION ACTIVE CONFORMATION OF THE VIRAL
The fusion of the influenza virus envelope with target membranes is mediated by haemagglutinin (or hemagglutinin, HA), the major spike membrane glycoprotein of influenza. The mature HA consists of two disulphide-linked subunits, HA1 and HA2. HA is organized as a homotrimer in the viral membrane. Subsequently to the endocytic uptake of influenza virus, at the acidic pH of endosomes a conformational change of the haemagglutinin ectodomain is triggered which activates its fusion capacity. Only the neutral pH, fusion-inactive structure of the bromelain-cleaved ectodomain of haemagglutinin has been known for one influenza strain from X-ray crystallography at 3 Angstrom resolution [1]. At neutral pH, the highly conserved N-terminus of the HA2 subunit is buried within the stem of the trimer 100 Angstrom away from the top of the HA spike [1]. Although several models have been proposed, the low pH, fusion competent structure of HA, in particular of its ectodomain, is unknown. The following contribution will represent our recent efforts to characterize the fusion competent conformation of HA.
