Mitochondria and plastids import proteins using mechanisms that have many features in common and yet each mechanism is sufficiently selective that only the appropriate set of proteins is imported. Protein selectivity is determined by discrete targeting sequences in mitochondrial and plastid precursor proteins and by large protein complexes that reside in the outer membrane of each organelle. In the mitochondrion, the translocase in the outer mitochondrial membrane controls protein import. One… CONTINUE READING
