Title: CRYSTAL STRUCTURE ANALYSIS OF AN RNA HEPTAMER Molecular Description: 5'-R(GpUpApUpApCpA)-3' Structural Features: SINGLE STRAND Nucleic Acid Sequence: Chains A, B: G U A U A C A Primary Citation: Shi, K., Pan, B., Sundaralingam, M. The crystal structure of an alternating RNA heptamer r(GUAUACA) forming a six base-paired duplex with 3'-end adenine overhangs Nucleic Acids Res. , 31, pp. 1392 - 1397, 2003. Experimental Information: X-RAY DIFFRACTION Space Group: C  2  2  2 Cell Constants: a = 25.740 b = 106.580 c = 30.260 (Ångstroms) = 90.00 = 90.00 = 90.00 (degrees) Crystallization Conditions: Drop: MPD, CaCl2, Cacodylate buffer Refinement: The structure was refined using the CNS program. The R value is 18 for 2808 reflections in the resolution range 20.00 to 2.01 Ångstroms with Fobs > 2.0 sigma(Fobs).
