Chain A   (CHER_SALTY | P07801)
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:0008983    protein-glutamate O-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + protein L-glutamate = S-adenosyl-L-homocysteine + protein L-glutamate 5-methyl ester; this reaction is the methylation of peptidyl-L-glutamate to form peptidyl-L-glutamate 5-methyl ester.
    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:0006935    chemotaxis    The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    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.
