| [[Pseudouridine]] is an abundant modified nucleoside found in RNA molecules. It is formed post-transcriptionally in RNA molecules by isomerization of the bond between base and ribose in uridine. There are two major types of enzymes that catalyze this reaction: | | [[Pseudouridine]] is an abundant modified nucleoside found in RNA molecules.
