(A) Steady-state protein levels. Mitochondria (Mitoch., μg protein) from wild-type (WT), crd1Δ and taz1Δ yeast grown at 21°C in liquid YPG were analyzed by SDS-PAGE and immunoblotting.
(B) Isolated mitochondria were analyzed by blue native electrophoresis and immunoblotting. The band at ~230 kDa in the Tom40 Western blot is only visible after long exposure.
(C) 2D-analysis. Isolated mitochondria were separated by blue native electrophoresis, followed by SDS-PAGE and immunoblotting.
(D) Oxa1 was imported into isolated BY mitochondria at 24°C in the absence of a Δψ. Samples were analyzed by blue native electrophoresis and autoradiography.
