Details CALCULATIONS WERE PERFORMED USING 232 CONFORMATIONALLY RESTRICTIVE NOE DERIVED DISTANCE CONSTRAINTS AND 55 BACKBONE AND 15 RIBOSE TORSION ANGLE CONSTRAINTS. BASE PAIR CONSTRAINTS WERE INTRODUCED FOR SIX BASE PAIRS USING HEAVY ATOM-HEAVY ATOM CONSTRAINTS. COORDINATES ARE FOR THE HAIRPIN DOMAIN ONLY. 5' FLANKING (GGCCAAA) AND 3' FLANKING (ACCCA) COORDINATES ARE NOT INCLUDED WITH THIS DEPOSITION. FEW CONSTRAINTS WERE OBTAINED FOR THESE VERY DYNAMIC REGIONS AND ALTHOUGH THEY WERE INCLUDED AS PART OF THE STRUCTURE CALCULATION, THEIR CONFORMATIONS APPEAR TO BE RANDOMLY DISTRIBUTED.
