    • note
    • Both molecules A and B contain residues 103 through 260. In the crystals, ≃50 percent of the RNA is nicked in lcop L6b between residues C237 and U238 [determined by direct RNA sequencing and primer extension analysis of RNA in crystals (unpublished data)]. For both molecules L6b has fairly continuous density in the experimental map for the backbone; the bases for nucleotides 236 through 239 have not been modeled. In each molecule, there are three to four residues-where the phosphate density is visible in the map but the base or ribose and base are not. In these cases, the full nucleotide has been included for refinement, but the occupancy for the missing component has been set to zero.

    • Free radicals produced by Fe(II)-EDTA in solution (presumably ·OH) cleave RNA without substantial specificity for base sequence or single- or doublestrandedness and therefore are useful for probing the solvent accessibility of elements within complex folded RNAs (3-5).

    • note
    • The two molecules (A and B) in the asymmetric unit of the crystal show different degrees of order at the 5′ end. In molecule B, clear density is seen in the solvent-flattened experimental map for all but the first G of the sequence; in molecule A, the density is weak for the first 4 nt of the sequence.
