Chain A (PRMC_ECOLI | P0ACC1)

molecular function
	GO:0008757	S-adenosylmethionine-dependent methyltransferase activity	Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate.
	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:0008276	protein methyltransferase activity	Catalysis of the transfer of a methyl group (CH3-) to a protein.
	GO:0036009	protein-glutamine N-methyltransferase activity	Catalysis of the reaction: S-adenosyl-L-methionine + protein L-glutamine = S-adenosyl-L-homocysteine + protein N-methyl-L-glutamine.
	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:0018364	peptidyl-glutamine methylation	The addition of a methyl group to a glutamine residue in a protein.
	GO:0006479	protein methylation	The addition of a methyl group to a protein amino acid. A methyl group is derived from methane by the removal of a hydrogen atom.
	GO:0010468	regulation of gene expression	Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
	GO:0006415	translational termination	The process resulting in the release of a polypeptide chain from the ribosome, usually in response to a termination codon (UAA, UAG, or UGA in the universal genetic code).
