详细说明

Toronto Research Chemicals - P839605

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. Stu
