CC   -!- FUNCTION: Methylation of the membrane-bound methyl-accepting chemotaxis
CC       proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP.
CC       {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-glutamyl-[protein] + S-adenosyl-L-methionine = [protein]-L-
CC         glutamate 5-O-methyl ester + S-adenosyl-L-homocysteine;
