The interaction of a peptide identical to the carboxy terminal region of the envelope glycoprotein gp41 828 of HIV with negatively charged phospholipids in a monolayer was studied by a Wilhelmy film balance. No significant interaction of the peptide with a monolayer composed of pure neutral but a strong affinity to negatively charged phospholipids could be observed. In mixed phospholipid monolayers...
This study focuses on the structural organization of surfactant protein B (SP-B) containing lipid monolayers. The artificial system is composed of the saturated phospholipids dipalmitoylphosphatidylcholine (DPPC) and dipalmitoylphosphatidylglycerol (DPPG) in a molar ratio of 4:1 with 0.2 mol% SP-B. The different “squeeze-out” structures of SP-B were visualized by scanning probe microscopy and compared...
