Molecular Description:5'-R(Up(BGM)GpApGpGpU)-3'
Structural Features:QUADRUPLE HELIX
Nucleic Acid Sequence:
ChainA:U (BGM) A G G U
Primary Citation:Pan, B.C., Xiong, Y., Shi, K., Sundaralingam, M.
An Eight-Stranded Helical Fragment in RNA Crystal Structure: Implications for Tetraplex Interaction
Structure , 11, pp. 825 - 831, 2003.
Experimental Information:X-RAY DIFFRACTION
Space Group: 2
Cell Constants:
a = 35.956b = 35.956c = 38.045(Ångstroms)
= 90.00 = 90.00 = 90.00(degrees)
Refinement:The structure was refined using the CNS program. The R value is 17.2 for 3763 reflections in the resolution range 30.0 to 1.50 Ångstroms with Fobs > 2.0 sigma(Fobs).
