Detection of Q-modification in RNAs from S. pombe and S. flexneri via reverse transcription using RT-KTq I614Y (Q-MaP-Seq)


ABSTRACT: In most eukaryotes and bacteria, queuosine (Q) replaces the guanosine at the wobble position of tRNAs harboring a GUN anticodon. To faithfully detect Q-modification in RNAs from Schizosaccharomyces pombe and Shigella flexneri, Q-MaP-Seq was established and applied to tRNAs from S. pombe WT (AEP1) cells and Shigella flexneri WT cells and tgt∆ cells. Q-modification of in vitro-transcribed RNAs and RNAs isolated from S. pombe and S. flexneri followed by reverse transcription using the RT-active DNA polymerase variant RT-KTq I614Y and sequencing of unmodified compared to modified RNAs allowed identification of Q-sites within tRNAs.
