GO:0006396 Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules. GO:0008649 Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a nucleoside residue in an rRNA molecule. The methyl group can be transfered to the nucleobase or to the ribose group of the nucleoside. GO:0001510 Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor. GO:0008757 Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate. GO:0008168 Catalysis of the transfer of a methyl group to an acceptor molecule. GO:0003723 Binding to an RNA molecule or a portion thereof.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

55 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
