Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (NSHR_STRAS | P52391)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0008173    RNA methyltransferase activity    Catalysis of the transfer of a methyl group from a donor to a nucleoside residue in an RNA molecule.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0008649    rRNA methyltransferase activity    Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a nucleoside residue in an rRNA molecule.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0001510    RNA methylation    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:0006396    RNA processing    Any process involved in the conversion of one or more primary RNA transcripts into one or more mature RNA molecules.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0031167    rRNA methylation    The posttranscriptional addition of methyl groups to specific residues in an rRNA molecule.
    GO:0046677    response to antibiotic    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
