説明β-Pseudouridine is the C-5 glycoside isomer of the nucleoside uridine. It is formed when uridine in RNA undergoes site-specific isomerization by a pseudouridine synthase enzyme. Pseudouridine is found in tRNAs from bacteria, archaea, and eukaryotes. In vitro, it reduces the number of X-ray-induced chromosomal aberrations in human lymphocytes isolated from whole blood in a dose-dependent manner.
使用An isomer of the nucleoside uridine found in all species and in many classes of RNA except mRNA. It is formed by enzymes called Ψ synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation. Studies suggest that β-Pseudouridine reduces radiation-induced chromosome aberrations in human lymphocytes.
