Chain A (TRMB_ECOLI | P0A8I5)

molecular function
	GO:0008168	methyltransferase activity	Catalysis of the transfer of a methyl group to an acceptor molecule.
	GO:0008176	tRNA (guanine-N7-)-methyltransferase activity	Catalysis of the reaction: S-adenosyl-L-methionine + tRNA = S-adenosyl-L-homocysteine + tRNA 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:0036265	RNA (guanine-N7)-methylation	The addition of a methyl group to the N7 atom in the base portion of a guanine nucleotide residue in an RNA molecule.
	GO:0032259	methylation	The process in which a methyl group is covalently attached to a molecule.
	GO:0030488	tRNA methylation	The posttranscriptional addition of methyl groups to specific residues in a tRNA molecule.
	GO:0006400	tRNA modification	The covalent alteration of one or more nucleotides within a tRNA molecule to produce a tRNA molecule with a sequence that differs from that coded genetically.
	GO:0008033	tRNA processing	The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group.
cellular component
	GO:0043527	tRNA methyltransferase complex	A multimeric protein complex involved in the methylation of specific nucleotides in tRNA.
