coa3Δ yeast cells are respiratory deficient and lack cytochrome oxidase. (A) Wild-type (WT), coa3Δ, and cox14Δ yeast cells were spotted in serial 10-fold dilutions on fermentable (glucose) and nonfermentable (glycerol) media. (B) Enzyme assays of isolated mitochondria. Means of four independent experiments (SEM; n = 4). (C) Solubilized mitochondria were separated by BN-PAGE and analyzed by Western blotting. (D) Mitochondria (Mito) were separated by SDS-PAGE and analyzed by Western blotting.
