Title: A 1.3 A RESOLUTION CRYSTAL STRUCTURE OF THE HIV-1 TRANS-ACTIVATION RESPONSE REGION RNA STEM REVEALS A METAL ION-DEPENDENT BULGE CONFORMATION Molecular Description: 5'-R(GpGpCpCpApGpApUpCpUpGpApGpCpG)-3' Structural Features: DOUBLE HELIX, BULGE, OVERHANGING BASES Nucleic Acid Sequence: Chain A: G G C C A G A U C U G A G C G Chain B: G C U C U C U G G C C C Primary Citation: Ippolito, J.A., Steitz, T.A. A 1.3-A resolution crystal structure of the HIV-1 trans-activation response region RNA stem reveals a metal ion-dependent bulge conformation. Proc.Natl.Acad.Sci.USA , 95, pp. 9819 - 9824, 1998. Experimental Information: X-RAY DIFFRACTION Space Group: P  1 Cell Constants: a = 27.100 b = 27.100 c = 31.600 (Ångstroms) = 69.20 = 77.50 = 63.00 (degrees) Refinement: The structure was refined using the SHELXL-97 program. The R value is 12.6 for reflections in the resolution range 20.000 to 1.300 Ångstroms with Fobs > 0.000 sigma(Fobs).
