The crystal structure of a 26-nucleotide RNA containing a hook-turn

TABLE 3.

Root-mean-square deviation between ribosomal hook-junctions and BCh12 calculated using the phosphorus atom positionsa

BCh12 A B C D
Nucleotides compared: BCh12 (S5–S10 and L7–L10); A, T. thermophilus 16S rRNA (G527–C532 and U481–C484), pdb: li94; B, D. radiodurans 23S rRNA (G645–U650 and G637–C640), pdb: 1kc9; C, H. marismortui 23S rRNA (A2255–A2260 and U2242– U2246); pdb: 1jj2; D, D. radiodurans 23S rRNA (C610–C615 and U667–U670) pdb: 1kc9.
aRight side of table shows values for only the turning strand (corresponding to S5–S10 of BCh12), left side show overlay of the complete junction (S5–S10 and L7–L10).
