大多数线粒体蛋白质在细胞质中合成并输入到四个线粒体隔室之一:外膜、膜间隙、内膜和基质。每个隔室含有与前体蛋白相互作用并促进其转运的蛋白质复合物。这些易位酶复合物不作为独立的单元,而是以动态的方式彼此合作并进一步与膜复合物合作。我们建议,转运酶的调节耦合是重要的前蛋白转运的协调和有效的排序intramitochondrial compartments。
Most mitochondrial proteins are synthesized in the cytosol and imported into one of the four mitochondrial compartments: outer membrane, intermembrane space, inner membrane, and matrix. Each compartment contains protein complexes that interact with precursor proteins and promote their transport. These translocase complexes do not act as independent units but cooperate with each other and further membrane complexes in a dynamic manner. We propose that a regulated coupling of translocases is important for the coordination of preprotein translocation and efficient sorting to intramitochondrial compartments.
