Legacy Theses & Dissertations (2009 - 2024)
RNA plays an essential role in many biological processes by acting as both genetic information carriers, catalyst and regulator. Natural RNAs usually contain nucleoside analogs from the four common ribonucleosides. There are over 150 chemical modification have been discovered in natural RNA molecules. 5-cyanomethyl uridine is a native modification that has been discovered in total tRNAs from Haloarcula marismortui. This modification in the anticodon wobble position affects the codon recognition, and leads the mutant tRNA to bind not only to AUA but also to AUU and AUG. We synthesized 5-cyanomethyl uridine (cnm5U) and its derivative 5-cyanouridine (cn5U), which has the …
