AUTOMATED BACKBONE ASSIGNMENTS WERE MADE USING AUTOASSIGN, AND THE SIDE CHAIN ASSIGNMENTS WERE COMPLETED MANUALLY. AUTOMATIC NOESY ASSIGNMENTS AS WELL AS DISTANCE AND HYDROGEN BOND CONSTRAINTS WERE DETERMINED USING AUTOSTRUCTURE. DIHEDRAL ANGLE CONSTRAINTS WERE DETERMINED USING HYPER. COMPLETENESS OF NMR ASSIGNMENTS (EXCLUDING N-TERMINAL MET AND C-TERMINAL HHHHHH): BACKBONE, 99.8%, SIDE CHAIN, 95.3%, AROMATICS, 100%, STEREOSPECIFIC METHYL, 95.2%.

STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING AUTOSTRUCTURE (XPLOR-NIH). AFTER A FINAL XPLOR CALCULATION USING THE CONSTRAINTS DERIVED FROM AUTOSTRUCTURE, THE 20 LOWEST ENERGY STRUCTURES OUT OF 100 WERE FURTHER REFINED BY RESTRAINED MOLECULAR DYANMICS/ENERGY MINIMIZATION IN EXPLICIT WATER (CNS). THE N-TERMINAL MET AND UNSTRUCTURED C-TERMINUS OF THE PROTEIN (LRGG + LEHHHHHH TAG) WERE INCLUDED IN ALL STRUCTURE CALCULATIONS BUT HAVE BEEN OMITTED FROM THIS DEPOSITION.
