(F) Mitochondria from the indicated yeast strains (pex19Δ, pex19Δmsp1Δ, and pex13Δmsp1Δpex19Δ) expressing Pex22-V5 (under its endogenous promotor) (HistodenzTM-purified) were separated by SDS-PAGE and immunoblotted for Pex22-V5 (α-Pex22-V5) and porin (α-porin). (G) Mitochondria from the indicated yeast strains (pex19Δ, pex19Δmsp1Δ, and pex13Δmsp1Δpex19Δ ) expressing Pot1-V5 (under its endogenous promotor) were separated by SDS-PAGE and immunoblotted for Pot1-V5 (α-Pot1-V5) and porin (α-porin). (H) Mitochondria from the indicated yeast strains (pex19Δ, pex19Δmsp1 Δ, and pex13Δmsp1Δpex19Δ) expressing Mdh3-V5 (under its endogenous promotor) (HistodenzTM-purified) were separated by SDS-PAGE and immunoblotted for Mdh3-V5 (α-Mdh3-V5) and porin (α-porin).
