FIGURE 6.

Chemical probing of the T275:tRNAGly complex using a (A) proteinogenic (P1) and a (B) nonproteinogenic (NP2) tRNAGly; (S) indicates strong and (W) weak base modifications by DMS or KE; (C) indicates the unmodified control reaction. Primers TbGL_1 and TbGl_6 (Supplemental Table 1) were used for stem I and antiterminator region analysis, respectively. (C) Predicted antiterminator structure and base modification protection by tRNAGly binding. Filled black stars correspond to specific protection by P1 tRNAGly(GCC) and open stars to protection by NP2 tRNAGly(UCC). Highly conserved (100%) and moderately conserved (66%) nucleotides are indicated with gray filled or open circles, respectively.
