SOLUTION NMR STRUCTURE OF THE MITOCHONDRIAL PROTEIN IMPORT RECEPTOR TOM20 FROM RAT IN A COMPLEX WITH A PRESEQUENCE PEPTIDE DERIVED FROM RAT ALDEHYDE DEHYDROGENASE (ALDH)


Overview

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 alpha-helical structure with a groove to accommodate the presequence peptide. The bound presequence forms an amphiphilic helical structure with hydrophobic leucines aligned on one side to interact with a hydrophobic patch in the Tom20 groove. Although the positive charges of the presequence are essential for import ability, presequence binding to Tom20 is mediated mainly by hydrophobic rather than ionic interactions.
