Última Ultrastructural analysis and identification of membrane proteins in the free-living amoeba Difflugia corona Biocell Silva-Briano,Marcelo; Martínez-Hernández,Sandra Luz; Adabache-Ortíz,Araceli; Ventura-Juárez,Javier; Salinas,Eva; Quintanar,J. Luis. Syntaxin-1 and 25-kDa Synaptosome-associated Protein (SNAP-25) are present in the plasma membrane of several different secretory cell types and are involved in the exocytosis process. In this work, the free-living amoeba Difflugia corona was studied in relation to ultrastructure, structural membrane proteins, and proteins such as Syntaxin-1 and SNAP-25. Our results obtained by scanning electron microscopy in the amoeba without its theca, showed many membrane projections and several pore-like structures. Using immunocytochemistry, we found structural proteins Syntaxin-1 and SNAP-25. Tipo: Info:eu-repo/semantics/article Palavras-chave: Amoeba; Membrane proteins; Pore-like; Theca; Ultrastructure.

Reconstitution of membrane proteins into lipid bilayers is a powerful tool to analyze functional as well as structural areas of membrane protein research. First, the proper incorporation of a purified membrane protein into closed lipid vesicles, to produce proteoliposomes, allows the investigation of transport and/or catalytic properties of any membrane protein without interference by other membrane components. Second, the incorporation of a large amount of membrane proteins into lipid bilayers to grow crystals confined to two dimensions has recently opened a new way to solve their structure at high resolution using electron crystallography. However, reconstitution of membrane proteins into functional proteoliposomes or 2-D crystallization has been an...

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2002000700001 The effect of hydrostatic pressure on membrane-bound proteins BJMBR Scarlata,S.. Many cellular proteins are bound to the surfaces of membranes and participate in various cell signaling responses. Interactions between this group of proteins are in part controlled by the membrane surface to which the proteins are bound. This review focuses on the effects of pressure on membrane-associated proteins. Initially, the effect of pressure on membrane surfaces and how pressure may perturb the membrane binding of proteins is discussed. Next, the effect of pressure on the activity and lateral association of proteins is considered. We then discuss how pressure can be used to gain insight into these types of proteins.

A panel of 13 monoclonal antibodies (MAbs) that react against outer membrane proteins of Salmonella Enteritidis was obtained. Two MAbs were classified as IgM, six were IgG2a, three were IgG3 and one was of the IgG2b isotype. The reactivity of the MAbs against different serovars of Salmonella enterica and other bacteria was investigated using an indirect ELISA. Five MAbs reacted only against Salmonella Enteritidis. Two MAbs presented crossed reactions with thermo-extracted antigens of Klebsiella pneumoniae, Citrobacter freundii and Enterobacter aerogenes. MAb 424H presented wide spectrum of reactivity, detecting antigens of Salmonella belonging to serogroups B, C, D, E and G. The detection limit of different serovars of Salmonella in a indirect ELISA with... Tipo: Info:eu-repo/semantics/article Palavras-chave: Salmonella; Monoclonal antibodies; Membrane proteins; Foods.
