Cholesterol incorporation into bacterial membranes.
The wall-covered bacteria Micrococcus lysodeikticus, Bacillus megaterium, and Proteus mirabilis incorporated exogenous cholesterol into their cytoplasmic membrane in quantities resembling those incorporated by sterol-nonrequiring mycoplasmas. Cholesterol incorporation into the outer membrane of P. mirabilis was much more restricted than into the cytoplasmic membrane.
متن کاملIncorporation of Fatty Acids into Phospholipids of Erythrocyte Membranes.
Incorporation of C14-labeled fatty acids into phospholipids by washed ghosts, prepared from human erythrocytes, required the addition of ATP and was markedly stimulated by MgC12 and coenzyme A. Labeled palmitic acid from l-C"-palmitoyl CoA was incorporated in the absence of added cofactors, The extent of incorporation of linoleic acid was greater than that of oleic, palmitic, or stearic acids. ...
متن کاملIncorporation of connexins into plasma membranes and gap junctions.
Gap junctions are polymeric assemblies of aligned pairs of interacting hexameric connexon hemichannel units facilitating direct intercellular communication. The principal process leading to assembly of gap junctions involves the cotranslational insertion of connexin (Cx) proteins into the endoplasmic reticulum, followed by their rapid oligomeric association into homo- or heteromeric connexons t...
متن کاملIncorporation of UDP-[C]Glucose into Xyloglucan by Pea Membranes.
The water-insoluble 1,4-beta-linked products formed from UDP-[(14)C]glucose by pea membranes were dissolved in hot dimethyl-sulfoxide/paraformaldehyde and fractionated on columns of controlled pore glass beads calibrated with dextran standards. The products eluted with a peak size close to 70 kilodaltons in dextran equivalents. Similar elution profiles were obtained for products formed in brief...
متن کاملActivation of mast cells by incorporation of cholesterol into rafts.
IgE plus antigen-stimulated mast cells degranulate, synthesize leukotrienes and secrete cytokines. According to the coalescence model this process is initiated in specific membrane compartments termed rafts. There, enhanced levels of glycosphingolipids and cholesterol stabilize the interaction of FcepsilonRI and Lyn, and thus facilitate the first steps of signal transduction. Enforced changes i...
