Among different RNA modifications, the helix 69 (H69) region of the bacterial ribosomal RNA (rRNA) contains three pseudouridines (Ψs). H69 is functionally important due to its location in the heart of the ribosome. Several structural and functional studies have shown the importance of Ψ modifications in influencing the H69 conformation as well as maintaining key interactions in the ribosome during protein synthesis. Therefore, a need exists to understand the influence of modified nucleosides on conformational dynamics of the ribosome under solution conditions that mimic the cellular environment. In this review on chemical probing, we provide detailed protocols for the use of dimethyl sulfate (DMS) to ex... More
