THE INTRA- REMARK 210 PEPTIDE NOES AND INTERMOLECULAR NOES WERE COLLECTED AT PH6.8 REMARK 210 IN THE ABSENCE OF CHAPSO USING 2D AND 3D NOESY SPECTRA WITH REMARK 210 ISOTOPE FILTERS. THE NOE ASSIGNMENT WAS COMPLETED BY USING REMARK 210 SEQUENCE- SPECIFICALLY DEUTERATED DERIVATIVES OF THE PEPTIDE. REMARK 210 THESE THREE NOE SETS WERE COMBINED TO CALCULATE THE COMPLEX REMARK 210 STRUCTURE OF TOM20 AND THE PRESEQUENCE PEPTIDE.
