title: Interaction of the mitochondrial ATPase complex with phospholipids.
abstract: The interaction of bovine heart mitochondrial oligomycin-sensitive ATPase (Serrano, R., Kranner, B. L., and Racker, E. (1976) J. Biol. Chem. 251, 2453-2461) with phospholipids has been examined by labeling the subunits exposed to lipids with photoreactive radioactive phospholipids. A subunit of Mr = 29,000 and some polypeptides in the range of 6,000 to 13,000 daltons were labeled. F1-ATPase subunits did not interact with the photoactive probes. This result is compared with the different pattern of labeling obtained with another mitochondrial ATPase preparation (Galante, Y.M., Wong, S. Y., and Hatefi, Y. (1979) J. Biol. Chem. 254, 12372-12378), which is devoid of the 29,000 component.
