Pseudouridine (abbreviated by the Greek letter psi- psi) is an isomer of the nucleoside uridine in which the uracil is attached via a carbon-carbon instead of a nitrogen-carbon glycosidic bond. It is the most prevalent of the over one hundred different modified nucleosides found in RNA. psi is found in all species and in many classes of RNA. psi is formed by enzymes called psi synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation.
