NMR SOLUTION STRUCTURE OF THE RNA HAIRPIN BINDING SITE FOR THE HISTONE STEM-LOOP BINDING PROTEIN
NMR structure and dynamics of the RNA-binding site for the histone mRNA stem-loop binding protein.
THIS STRUCTURE WAS DETERMINED USING A VARIETY OF 2D AND 3D HOMO- AND HETERO-NUCLEAR NMR METHODS.
1JU7 is the Overlay of 10 converged structures from which this average structure was produced.
THIS SEQUENCE OCCURS NATURALLY AT THE 3' END OF THE REPLICATION-DEPENDENT HISTONE MRNAS OF VERTEBRATES. THIS SEQUENCE CORRESPONDS TO THE MOUSE H4-12 GENE.
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.
