Deskripsi
The small modified nucleotide PreQ1 binds to the PreQ1 riboswitch and regulates gene expression by inducing RNA conformation change. Here the authors design and characterize a specific preQ1-derived probe by x-ray crystallography, mass spectral analysis and transcriptome-wide using Chem-CLIP.
