1. The polypeptide composition of purified QH2: cytochrome c oxidoreductase prepared by three different methods from beef-heart mitochondria has been determined. Polyacrylamide gel electrophoresis in the presence of dodecyl sulphate resolves eight intrinsic polypeptide bands; when, in addition, 8 M urea is present and a more highly cross-linked gel is used, the smallest polypeptide band is resolved into three different bands. 2. The identity of several polypeptide bands has been established by fractionation. The two heaviest polypeptides (bands 1 and 2) represent the so-called core proteins, band 3 the hemoprotein of cytochrome b, band 4 the hemoprotein of cytochrome c1, band 5 and Rieske Fe-S protein, band 6 a polypeptide associated with cytochrome c1 and identified with the so-called oxidation factor, and band 7 a polypeptide peptide associated with cytochrome b. 3. The validity of molecular weight estimate for the polypeptides of the enzyme based on their mobility on dodecyl sulphate gels has been examined. The polypeptides of bands 1, 2 and 3 showed anomalous migration rates. The molecular weights of the other polypeptides have been estimated from their relative mobilities on either dodecyl sulphate gels or 8 M urea-dodecyl sulphate gels as 29 000, 24 000, 12 000, 8000, 6000, 5000 and 4000, respectively. 4. The stoicheiometry of the different polypeptides in the intact complex was determined using separate staining factors for the individual polypeptide band. << Less
