Title: CRYSTAL STRUCTURE A DNA:RNA HYBRID DUPLEX, A DYNAMIC MODEL FOR RNASE H RECOGNITION Molecular Description: 5'-D(CpTpCpTpTpCpTpTpC)-3' 5'-R(GpApApGpApApGpApG)-3' Structural Features: A DOUBLE HELIX Nucleic Acid Sequence: Chain A: (DC) (DT) (DC) (DT) (DT) (DC) (DT) (DT) (DC) Chain B: G A A G A A G A G Primary Citation: Xiong, Y., Sundaralingam, M. Crystal structure of a DNA.RNA hybrid duplex with a polypurine RNA r(gaagaagag) and a complementary polypyrimidine DNA d(CTCTTCTTC). Nucleic Acids Res. , 28, pp. 2171 - 2176, 2000. Experimental Information: X-RAY DIFFRACTION Space Group: P  61 Cell Constants: a = 49.15 b = 49.15 c = 46.13 (Ångstroms) = 90.0 = 90.0 = 120.00 (degrees) Crystallization Conditions: Method: VAPOR DIFFUSION, HANGING DROP Drop: MgCl2, SODIUM CACODYLATE, SPERMINE TETRACHLORIDE, MPD Reservoir: MPD Refinement: The structure was refined using the X-PLOR 3.851 program. The R value is 19.9 for 4373 reflections in the resolution range 10.0 to 1.9 Ångstroms with Fobs > 2.0 sigma(Fobs).
