Cytochrome c Oxidase from Bakers’ Yeast
Purified cytochrome c oxidase from bakers’ yeast can be resolved into six polypeptide bands by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The apparent molecular weights of these components are I, 42,000; II, 34,500; III, 23,000; IV, 14,000; V, 12,500; and VI, 9,500. (Although Component V actually consists of two distinct polypeptide species, it will be regarde...
متن کاملCytochrome c Oxidase from Bakers’ Yeast
Cytochrome aa3 was purified 35to 40-fold from submitochondrial particles of commercial bakers’ yeast. The purification procedure involved solubilization of the enzyme with cholate, fractionation with ammonium sulfate, and chromatography on DEAE-cellulose in the presence of Triton x-100. The purified, active enzyme contained approximately 10 nmoles of heme a per mg of protein and was free of oth...
متن کاملDistribution of cytochrome c peroxidase activity in wild-type and petite cells of bakers' yeast grown aerobically and anaerobically.
Studies of mitochondrial biogenesis in yeast have been hampered by a lack of suitable membrane markers in anaerobically grown cells subsequently grown in air. Cytochrome c peroxidase activity and subcellular location was studied to determine whether it would be a useful marker for an analysis of mitochondrial formation. Cytochemical tests revealed enzyme reaction product on all mitochondrial me...

متن کاملDNA polymerases from bakers' yeast.
Two DNA polymerases are present in extracts of commercial bakers' yeast and wild type Saccharomyces cerevisiae grown aerobically to late log phase. Yeast DNA polymerase I and yeast DNA polymerase II can be separated by DEAE-cellulose, hydroxylapatite, and denatured DNA-cellulose chromatography from the postmitochondrial supernatants of yeast lysates. The yeast polymerases are both of high molec...
