General Information
Term rRNA methyltransferase activity ID (Ontology) GO:0008649 (Gene Ontology)
Definition 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.
