FIGURE 7.

Schematic representation of the proposed S. aureus glyS T-box:tRNAGly recognition model. (Left panel) S. aureus glyS T-box structural rearrangement upon P1 tRNAGly GCC isoacceptor binding. Nucleotides in black that are presented on T-box structure indicate additional interactions with P1 isoacceptor, according to the data presented herein. (Right panel) The corresponding T-box structural rearrangement upon binding of the remaining tRNAGly UCC isoacceptors. Nucleotides in gray represent common interaction with either GCC or UCC bearing tRNAs. Nucleotides on tRNAs correspond to major sequence differences among isoacceptors (Supplemental Fig. 2), namely, positions 18, 19, 33–36, 55, 56, 73–76.
