molecular function
    GO:0052908    16S rRNA (adenine(1518)-N(6)/adenine(1519)-N(6))-dimethyltransferase activity    Catalysis of the reaction: 4 S-adenosyl-L-methionine + adenine(1518)/adenine(1519) in 16S rRNA = 4 S-adenosyl-L-homocysteine + N(6)-dimethyladenine(1518)/N(6)-dimethyladenine(1519) in 16S rRNA.
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0016433    rRNA (adenine) methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + rRNA = S-adenosyl-L-homocysteine + rRNA containing methyladenine.
    GO:0000179    rRNA (adenine-N6,N6-)-dimethyltransferase activity    Catalysis of the dimethylation two adjacent A residues in the loop closing the 3'-terminal stem of the 18S rRNA, using S-adenosyl-L-methionine as a methyl donor.
    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: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:0000154    rRNA modification    The covalent alteration of one or more nucleotides within an rRNA molecule to produce an rRNA molecule with a sequence that differs from that coded genetically.
    GO:0006364    rRNA processing    Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
