Fig. 5.

Chemical probing of interactions of LC (filled arrowheads), LM (open arrowheads) and ERY (open circles) with the ribosome. Protection of 23S rRNA residues from (A) CMCT and (B) DMS modification by LC. (C) Protection of 23S rRNA residues from CMCT modification by LM. (D) Protections from CMCT afforded by LC, LM, and ERY present alone or in combination. Small open circles indicate bands that appeared because of slight nuclease degradation, which were not reproducible between the repeated experiments.
