Details secondary structural elements (3 helices) were identified. these were split into smaller fragments and individual fragments were oriented using residual dipolar coupling data and the program Orderten_SVD (Losonczi, et al., J. Magn. Res., 138, 334-342, 1999). The fragments were reassembled and then positioned spatially by translation using a limited set of NOEs to produce a backbone fold of the nodF protein. THERE ARE N-CA-C ANGLE ERRORS (AS COMPARED TO THE STANDARD DICTIONARY) AT RESIDUES 13 AND 80. RESIDUE 80 LIES SOMEWHAT OUTSIDE ALLOWED RAMACHANDRAN SPACE. THESE SITES ARE POSITIONS WHERE ORIENTED HELICAL FRAGMENTS WERE REASSEMBLED INTO COMPLETE HELICES DURING DETERMINATION OF OF THE BACKBONE FOLD AND ANY SMALLER LOCAL DISTORTIONS FROM IDEALITY ARE EXPECTED TO CONCENTRATE HERE. THE STRUCTURE PRESENTED HERE CONTAINS ONLY COORDINATES FOR BACKBONE ATOMS INVOLVED IN SECONDARY STRUCTURE. THE STRUCTURE IS THE AVERAGE OF AN ENSEMBLE WITH A HEAVY ATOM RMSD OF 2.4 ANGSTROMS. CB POSITIONS COME FROM POLYALANINE HELICES USED TO MODEL THE BACKBONE.

Additional NMR Experimental Information
1 Assignments were made using double and triple-resonance NMR spectroscopy. Dipolar couplings were measured and used to produce the protein backbone fold.
