Deletion of the SRL causes structural changes in 23S rRNA. Primer-extension analysis of 23S rRNA extracted from WT or ΔSRL 50S subunits probed with D, dimethylsufate, or K, kethoxal. A and G are sequencing lanes; (−) unmodified subunits. Arrows indicate bases with altered reactivity in ΔSRL 50S subunits as compared to WT.
