abstract = {Thionins, ubiquitous plant toxins, are believed to act by
lysing the membrane of pathogenic organisms. Several
competing mechanisms were proposed for the lysis of
phospholipid membranes by the toxins. In order to study in
more detail the proposed mechanisms and possibly resolve
among the competing proposals, the interactions of
purothionins with a model lipid membrane in the form of a
monolayer were studied. The monolayer formed at the
air-water interface was studied by synchrotron X-ray
reflectivity and grazing incidents diffraction methods. The
model membrane was composed of 90:10 $mol\%$ DPPC:DPPS
(dipylmitoyl phosphatidylcholine:dipylmitoyl
phosphatidylserine). The protein interaction with the
monolayer disturbs the in-plane and out-of-plane order of
phospholipids, increases the amount of the liquid phase of
the monolayer, and increases the average surface area per
alkyl chain. The results indicate that the protein is bound
only transiently, and after approximately 4 h most of the
properties of the monolayer are reminiscent of the pure DPPC
monolayer suggesting partial withdrawal of DPPS. Obtained
electron density distributions perpendicular to the membrane
interface do not show any significant contribution from the
adsorbed proteins, further supporting the withdrawal
hypothesis.},
