Chain A,B (RLMKL_ECOLI | P75864)

molecular function
	GO:0052915	23S rRNA (guanine(2445)-N(2))-methyltransferase activity	Catalysis of the reaction: S-adenosyl-L-methionine + guanosine(2445) in 23S rRNA = N(2)-methylguanosine(2445) in 23S rRNA + S-adenosyl-L-homocysteine.
	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:0003676	nucleic acid binding	Interacting selectively and non-covalently with any nucleic acid.
	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:0008990	rRNA (guanine-N2-)-methyltransferase activity	Catalysis of the reaction: S-adenosyl-L-methionine + rRNA = S-adenosyl-L-homocysteine + rRNA containing N2-methylguanine.
	GO:0070043	rRNA (guanine-N7-)-methyltransferase activity	Catalysis of the reaction: S-adenosyl-L-methionine + rRNA = S-adenosyl-L-homocysteine + rRNA containing N7-methylguanine.
	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:0070476	rRNA (guanine-N7)-methylation	The addition of a methyl group to the N7 atom in the base portion of a guanine nucleotide residue in an rRNA molecule.
	GO:0070475	rRNA base methylation	The addition of a methyl group to an atom in the nucleoside base portion of a nucleotide residue in an rRNA molecule.
	GO:0031167	rRNA methylation	The posttranscriptional addition of methyl groups to specific residues in an rRNA molecule.
	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.
