COMPLEX REMARK 3 1 CONSISTS OF CHAINS A AND C, AND COMPLEX 2 CONSISTS OF REMARK 3 CHAINS B AND D. RESIDUES 1-7 AND 141 OF CHAIN A ARE REMARK 3 DISORDERED. THE DENSITY FOR RESIDUES 8-70 OF CHAIN A WAS OF REMARK 3 SIGNIFICANTLY LOWER QUALITY THAN THE DENSITY FOR THE REMARK 3 REMAINDER OF THE ASYMMETRIC UNIT, AND THE QUALITY OF THE REMARK 3 MODEL FOR THIS N-TERMINAL DOMAIN IS LOWER THAN THAT OF THE REMARK 3 C-TERMINAL DOMAIN (RESIDUES 71-140). RESIDUES 1-70 AND 141 REMARK 3 OF CHAIN B ARE DISORDERED. THE RNA IS NUMBERED WITH THE E. REMARK 3 COLI NUMBERING TO FACILITATE COMPARISON WITH THE EXTENSIVE REMARK 3 BIOCHEMICAL DATA ON THE E. COLI RNA-L11 SYSTEM. THE E. COLI REMARK 3 RNA NUMBERING IS ALSO USED IN THE PRIMARY REFERENCE REMARK 3 DESCRIBING THIS STRUCTURE.
