Analysis of membrane protein complexes by blue native PAGE.
Blue native polyacryamide gel electrophoresis is a special case of native electrophoresis for high resolution separation of enzymatically active protein complexes from tissue homogenates and cell fractions. The method is powerful between 10 and 10,000 kDa. Also membrane protein complexes are separated well after solubilization of complexes with mild neutral detergents. The separation principle ...
متن کاملCharacterization of the preprotein translocon at the outer envelope membrane of chloroplasts by blue native PAGE.
The preprotein translocon at the outer envelope membrane of chloroplasts (Toc) mediates the recognition and import of nuclear-encoded preproteins into chloroplasts. Two receptor components, Toc159 and Toc34, and the channel Toc75 form the Toc complex. In this study, we have analyzed the molecular architecture and organization of the Toc complex by blue native PAGE (BN-PAGE), which is a high-res...
متن کاملBlue native polyacrylamide gel electrophoresis (BN-PAGE) for analysis of multiprotein complexes from cellular lysates.
Multiprotein complexes (MPCs) play a crucial role in cell signalling, since most proteins can be found in functional or regulatory complexes with other proteins (Sali, Glaeser et al. 2003). Thus, the study of protein-protein interaction networks requires the detailed characterization of MPCs to gain an integrative understanding of protein function and regulation. For identification and analysis...
متن کاملMammalian ATPsynthase monomer versus dimer profiled by blue native PAGE and activity stain.
Studies into the effects of oligomerization on F(0)F(1)ATPsynthase function are contradictory. We optimized the in-gel ATPase assay to investigate the functional differences of monomers versus dimers. In Triton X-100 extracts of heavy bovine heart mitochondria (HBHM) and mitoplasts, but not submitochondrial particles (MgATP-SMP), dimers had greater specific activity than monomers: at 30 degrees...
