Abstract After being deprived of solubilizing agent, the lipid-free cytochrome oxidase requires Triton X100 and additional phospholipid to obtain maximal activity. High levels of Triton X100 affect the interaction of phospholipid and cytochrome oxidase, thus decreasing the activity. In the terminal segment of the electron transport system, phospholipid serves not only to enhance the interaction between cytochromec and cytochromea, but also to maintain favorable molecular arrangements of reacting groups in both hemoproteins. The relationship between the enzyme activity and phospholipid content as well as the ultrastructure of the enzyme is discussed.
