title: Amino acid sequence of bovine heart cytochrome oxidase subunit IV (Albany).
abstract: The preliminary data on the amino acid sequence of subunit IV from bovine heart cytochrome oxidase (Albany) is presented. The subunit consists of 97 amino acids linked together in a single polypeptide chain. The sequence was established by the isolation, purification and sequencing of some of the tryptic, chymotryptic and thermolytic and Staphylococcus aureus protease peptides. This subunit is present in all cytochrome oxidase preparations. It corresponds to polypeptide VIa in cytochrome oxidase (Aachen) and subunit a in cytochrome oxidase (Eugene).
