Title: A-DNA DECAMER D(GCGGGCCCGC)-ORTHORHOMBIC CRYSTAL FORM Molecular Description: 5'-D(GpCpGpGpGpCpCpCpGpC)-3' ORTHORHOMBIC Structural Features: A DOUBLE HELIX Nucleic Acid Sequence: Chains A,B: (DG) (DC) (DG) (DG) (DG) (DC) (DC) (DC) (DG) (DC) Primary Citation: Ramakrishnan, B., Sundaralingam, M. Evidence for crystal environment dominating base sequence effects on DNA conformation: crystal structures of the orthorhombic and hexagonal polymorphs of the A-DNA decamer d(GCGGGCCCGC) and comparison with their isomorphous crystal structures. Biochemistry , 32, pp. 11458 - 11468, 1993. Experimental Information: X-RAY DIFFRACTION Space Group: P  21   21   21 Cell Constants: a = 24.900 b = 44.840 c = 47.970 (Ångstroms) = 90.00 = 90.00 = 90.00 (degrees) Refinement: The structure was refined using the X-PLOR program. The R value is 18.5 for 5450 reflections in the resolution range 8.000 to 1.700 Ångstroms with Fobs > 3.000 sigma(Fobs).
