Most mitochondrial proteins are synthesized in the cytosol as precursor proteins with a cleavable N-terminal presequence and are imported into mitochondria. We report here the NMR structure of a general import receptor, rat Tom20, in a complex with a presequence peptide derived from rat aldehyde dehydrogenase. The cytosolic domain of Tom20 forms an all(More)
Many mitochondrial proteins are synthesized in the cytosol as precursors with N-terminal presequences, and are imported into mitochondria with the aid of translocator protein complexes containing presequence-binding proteins. Tom20, a receptor protein which functions in an early step of the mitochondrial protein import, recognizes presequences with(More)
Mitochondria import most of their resident proteins from the cytosol, and the import receptor Tom20 of the outer-membrane translocator TOM40 complex plays an essential role in specificity of mitochondrial protein import. Here we analyzed the effects of Tom20 binding on NMR spectra of a long mitochondrial presequence and found that it contains two distinct(More)
