Lack of Coa1 stalls Mss51 in a 250-kD complex. (A) Mss51HA mitochondria were solubilized, and samples were split and incubated with indicated antibodies. Antibodies with bound material were precipitated with protein A–Sepharose, and unbound material was analyzed by BN-PAGE and Western blotting using anti-HA antibodies. Respiratory chain supercomplexes and carrier translocase (TIM22) were detected with anti-Cox1 or anti-Tim54 antibodies, respectively. (B) Mitochondria from the indicated mutants expressing Mss51HA were analyzed as in A. (C) Antibody depletion experiments were performed in coa1Δ mitochondria as in A. For comparison, untreated wild-type (WT) mitochondria were analyzed in lane 1.
