    1522   Pseudouridine Synthesis  The Intramolecular Conversion of Uridine to Pseudouridine Within an RNA Molecule. This Posttranscriptional Base Modification Occurs in TRNA RRNA and Snrnas. 
    9451   RNA Modification  The Covalent Alteration of One or More Nucleotides Within an RNA Molecule to Produce an RNA Molecule with a Sequence That Differs From That Coded Genetically. 
    3723   RNA Binding  Interacting Selectively and Non Covalently with an RNA Molecule or a Portion Thereof. 
    9982   Pseudouridine Synthase Activity  Catalysis of the Reaction: RNA Uridine = RNA Pseudouridine. Conversion of Uridine in an RNA Molecule to Pseudouridine by Rotation of the C1' N 1 Glycosidic Bond of Uridine in RNA to a C1' C5. 
    16866   Intramolecular Transferase Activity  Catalysis of the Transfer of a Functional Group From One Position to Another Within a Single Molecule.
