Title: A SINGLE 2'-HYDROXYL GROUP CONVERTS B-DNA TO A-DNA: CRYSTAL STRUCTURE OF THE DNA-RNA CHIMERIC DECAMER DUPLEX D(CCGGC)R(G)D(CCGG) WITH A NOVEL INTERMOLECULAR G.C BASE-PAIRED QUADRUPLET Molecular Description: 5'-D(CpCpGpGpCp)-R(Gp)-D(CpCpGpG)-3' Structural Features: A DOUBLE HELIX Nucleic Acid Sequence: Primary Citation: Ban, C., Ramakrishnan, B., Sundaralingam, M. A single 2'-hydroxyl group converts B-DNA to A-DNA. Crystal structure of the DNA-RNA chimeric decamer duplex d(CCGGC)r(G)d(CCGG) with a novel intermolecular G-C base-paired quadruplet. J.Mol.Biol. , 236, pp. 275 - 285, 1994. Experimental Information: X-RAY DIFFRACTION Space Group: P  21   21   21 Cell Constants: a = 26.630 b = 45.240 c = 47.990 (Ångstroms) = 90.00 = 90.00 = 90.00 (degrees) Refinement: The structure was refined using the X-PLOR program. The R value is 13.6 for 2753 reflections in the resolution range 8.000 to 1.900 Ångstroms with Fobs > 1.000 sigma(Fobs).
