Additional NMR Experimental Information
DetailsSEQUENTIAL ASSIGNMENT WAS OBTAINED BY ANALYSIS OF HNCA, CBCA(CO)NH, HAHB(CO)NH AND 15N- CORRELATED NOESY SPECTRA. DISTANCE CONSTRAINTS WERE COLLECTED FROM NOESY SPECTRA IN H2O AND D2O AND A 15N- CORRELATED NOESY SPECTRA THE 3JHNA COUPLING CONSTANTS FOR DIHEDRAL ANGLE CONSTRAINTS WERE DETERMINED FROM A HMQC-J SPECTRUM OF THE 15N-LABELED SAMPLE.
