Figure 6.
Subcompartmental distribution of assembly intermediates of complex III and IV. Wild-type and Δbcs1 cells were grown on complete media containing 2% galactose, chemically fixed, cryosectioned, and immunogold labeled for Cox2, Core1, and Rip. Quantification of the distribution of mitochondrial proteins was as described in Figs. 1 and 2 and Materials and methods. In the Δbcs1 strain, complex III is only partially assembled, and the supracomplexes III2IV2 are not formed.
