Vestigial ATP synthase complexes in HAP1 cells devoid of peripheral stalk subunits d and F₆. Subunit compositions of vestigial human ATP synthase complexes in HAP1-∆d and HAP1-∆F₆ cells. The vestigial complexes were immunopurified from digitonin extracts of mitoplasts, fractioned by SDS-PAGE, and proteins were detected with Coomassie blue dye. The positions of subunits are indicated on the left.
