The general preprotein translocase of the outer mitochondrial membrane (TOM complex) transports virtually all mitochondrial precursor proteins, but cannot assemble outer-membrane precursors into functional complexes. A recently discovered sorting and assembly machinery (SAM complex) is essential for integration and assembly of outer-membrane proteins, revealing unexpected connections to mitochondrial evolution and morphology.
线粒体外膜的一般前体蛋白转位酶(TOM复合体)几乎能转运所有线粒体前体蛋白,但无法将外膜前体组装成功能复合体。最近发现的分选与组装机制(SAM复合体)对于外膜蛋白的整合与组装至关重要,揭示了与线粒体进化和形态的意外联系。
