molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0019239 | | deaminase activity | | Catalysis of the removal of an amino group from a substrate, producing ammonia (NH3). |
| GO:0016853 | | isomerase activity | | Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0009982 | | 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. |
biological process |
| GO:0009451 | | 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. |
| GO:0000455 | | enzyme-directed rRNA pseudouridine synthesis | | The intramolecular conversion of uridine to pseudouridine during ribosome biogenesis where the enzyme specifies the site that becomes pseudouridylated without using a guide RNA. |
| GO:0001522 | | pseudouridine synthesis | | The intramolecular conversion of uridine to pseudouridine within an RNA molecule. This posttranscriptional base modification occurs in tRNA, rRNA, and snRNAs. |
| GO:0006364 | | rRNA processing | | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
| GO:0000027 | | ribosomal large subunit assembly | | The aggregation, arrangement and bonding together of constituent RNAs and proteins to form the large ribosomal subunit. |
cellular component |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
