Title: GUAA TETRALOOP MUTANT OF SARCIN/RICIN DOMAIN FROM E. COLI 23 S RRNA Molecular Description: SARCIN/RICIN DOMAIN FROM 23 S RRNA Structural Features: SINGLE STRAND, LOOP Nucleic Acid Sequence: Chain A: U G C U C C U A G U A C G U A A G G A C C G G A G U G Primary Citation: Correll, C.C., Swinger, K. Common and distinctive features of GNRA tetraloops based on a GUAA tetraloop structure at 1.4 A resolution RNA , 9, pp. 355 - 363, 2003. Experimental Information: X-RAY DIFFRACTION Space Group: C  1  2  1 Cell Constants: a = 57.974 b = 22.534 c = 58.465 (Ångstroms) = 90.00 = 101.72 = 90.00 (degrees) Crystallization Conditions: Method: VAPOR DIFFUSION, HANGING DROP Drop: (NH4)2SO4, potassium MOPS, MgCl2, MnCl2 Reservoir: (NH4)2SO4, MgCl2, MnCl2 Refinement: The structure was refined using the SHELXL-97 program. The R value is 16.4 for 14372 reflections in the resolution range 29.0 to 1.41 Ångstroms with I > 0.0 sigma(I).
