Mgr2 promotes Δψ-dependent protein import. (A) b2(84)-DHFR was imported into wild-type (WT), tim21Δ, and mgr2Δ mitochondria (cells grown at 30°C) in the presence of CCCP and analyzed by SDS-PAGE and autoradiography. Import without CCCP was set to 100% (control). The mean ± SEM (n = 4) is shown. (B and C) Preprotein import into mitochondria followed by SDS-PAGE. MTX, methotrexate; p, precursor; i, intermediate; m, mature.
