WebSwitch to Pseudouridine Researchers at CSMP have revealed how Escherichia coli cells modify uridine nucleotides in the anticodon stem loop of transfer RNA. TruA is a pseudouridine synthase that specializes in three positions in the tRNA, positions 38, 39, and 40. These positions are in the critical base-paired region adjacent to the anticodon. WebTRNA pseudouridine 65 synthase (EC 5.4.99.26, TruC, YqcB) is an enzyme with systematic name tRNA-uridine 65 uracil mutase. This enzyme catalyses the following chemical reaction. tRNA uridine 65 tRNA pseudouridine 65. TruC specifically modifies uridines at positions 65 in tRNA. References
WebFeb 1, 2024 · Pseudouridine synthases convert the usual N-C glycosidic bond between N1 of the uracil ring and the ribose sugar into a C-C bond involving C5. N1 becomes available to form additional hydrogen bonds (dashed lines) with a water molecule (red sphere) increasing the structural stability of the RNA.
