Analysis of mitochondrial subunit assembly into respiratory chain complexes using Blue Native polyacrylamide gel electrophoresis.
The mitochondrial respiratory chain consists of multi-subunit protein complexes embedded in the inner membrane. Although the majority of subunits are encoded by nuclear genes and are imported into mitochondria, 13 subunits in humans are encoded by mitochondrial DNA. The coordinated assembly of subunits encoded from two genomes is a poorly understood process, with assembly pathway defects being ...
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 کاملTwo-dimensional blue native/SDS gel electrophoresis of multiprotein complexes.
The two-dimensional blue native/sodium dodecyl sulfate polyacrylamide gel electrophoresis (2D BN/SDS-PAGE) is a method of choice for the investigation of protein complexes. This highly resolvent separation method is unique in that it facilitates the identification of many protein complexes simultaneously. Because of its simplicity and suitability, the 2D BN/SDS-PAGE can be now applied to a wide...
متن کاملFunctional characterization of reductive dehalogenases by using blue native polyacrylamide gel electrophoresis.
Dehalococcoides mccartyi strains are obligate organohalide-respiring bacteria harboring multiple distinct reductive dehalogenase (RDase) genes within their genomes. A major challenge is to identify substrates for the enzymes encoded by these RDase genes. We demonstrate an approach that involves blue native polyacrylamide gel electrophoresis (BN-PAGE) followed by enzyme activity assays with gel ...
متن کاملHigh-contrast imaging of chlorophyll-containing protein complexes separated by native polyacrylamide gel electrophoresis
Electrophoregrams with bands of green chlorophyll-containing protein complexes separated by native polyacrylamide gel electrophoresis (PAGE) are usually photographed in white light or scanned by a narrow beam of monochromatic light using densitometers. Present CCD cameras allow taking densitograms of a whole gel surface with many samples. However, commercial CCD imaging systems use mostly white...
