Additional NMR Experimental Information
1 THE INTRA-TOM20 PROTEIN NOES WERE OBTAINED AT PH5.4 AND 0.02M CHAPSO ( DETERGENT) IN THE ABSENCE OF THE PEPTIDE USING 3D 15N-RESOLVED AND 3D 13C- RESOLVED NOESY SPECTRA. THE INTRA-PEPTIDE NOES AND INTERMOLECULAR NOES WERE COLLECTED AT PH6.8 IN THE ABSENCE OF CHAPSO USING 2D AND 3D NOESY SPECTRA WITH ISOTOPE FILTERS. THE NOE ASSIGNMENT WAS COMPLETED BY USING SEQUENCE- SPECIFICALLY DEUTERATED DERIVATIVES OF THE PEPTIDE. THESE THREE NOE SETS WERE COMBINED TO CALCULATE THE COMPLEX STRUCTURE OF TOM20 AND THE PRESEQUENCE PEPTIDE.
