title: Electrophoretic behaviour of yeast mitochondrial translation products.
abstract: We have studied the mobility of yeast mitochondrial translation products during electrophoresis on polyacrylamide gels of different composition and found that these polypeptides can be divided into two groups. One, to which subunit II of cytochrome c oxidase belongs, behaves normal as all water-soluble reference proteins. The other, to which cytochrome b and subunits I and III of cytochrome c oxidase belong, shows a free electrophoretic mobility about twice as fast as the first group. Conditions have been found to separate cytochrome c1 from cytochrome b.
