title: The use of orthacryl two-dimensional polyacrylamide gel electrophoresis to identify and compare the subunit polypeptides of bovine heart and yeast cytochrome c oxidases.
abstract: A two-dimensional electrophoretic method which takes advantage of the "migration anomalies" experienced by some polypeptides on gels of different porosities has been successfully used to resolve the seven subunit polypeptides of yeast cytochrome c oxidase and the nine polypeptides associated with bovine cytochrome c oxidase. The two-dimensional maps provided by this method reveal clear differences between these two cytochrome c oxidases.
