ANALYSIS OF THE PROTEIN SUBUNIT STRUCTURE OF THE OLIGOMYCIN SENSITIVE ATPASE PROTEOLIPID FRACTION BY REVERSE PHASE HIGH-PRESSURE LIQUID-CHROMATOGRAPHY

The proteolipid fraction which is obtained from the bovine mitochondrial oligomycin sensitive ATPase complex by extraction with chloroform:methanol is resolvable into 7 components by preparative reverse phase high pressure liquid chromatography. Each of these 7 components is present together with 4 additionally resolved components in the proteolipid fraction which is obtained by extraction of submitochondrial particles with chloroform: methanol. Of the 7 components derived from the oligomycin sensitive ATPase, 4 have been identified with known protein subunits of the membrane sector of this complex, 2 are newly documented subunits of this complex, and 1 remains uncharacterized. © 1979.
