Our results provide a detailed framework for understanding the mechanisms of MprF-mediated modification and translocation of phospholipids. WebNov 2, 2016 · A similar technique is used here to study the size-dependent insertion and translocation of NPs through the phospholipid bilayer. Details of the applied simulations are described in Materials and Methods. NPs are modeled as hydrophobic spheres ( 47 ), with diameters ranging from 2 to 10 nm.
WebGram-negative bacteria to the other. Translocation of lipo-polysaccharide to the outer membrane appears to be an irre-versible process (7), but phospholipid translocation takes place bidirectionally (8). In an attempt to gain an understanding of the mechanism of phospholipid translocation, we have investigated how this Webgenerally accepted that spontaneous phospholipid translocation (also known as flip-flop) across a bilayer membrane is a very slow process and is facilitated by membrane-bound …
WebJun 29, 2024 · Phospholipid translocases that also belong to the “scramblase” group are the proteins that mediate PtdSer exposure on the cell surface during apoptosis and blood coagulation. In this chapter, to promote clarity, we will follow the new nomenclature and use the terms “flippase”, “floppase” and “scramblase” as described above.
