CC -!- FUNCTION: Methylation of the membrane-bound methyl-accepting chemotaxis
CC proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP.
CC {ECO:0000256|PIRNR:PIRNR000410}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutamyl-[protein] + S-adenosyl-L-methionine = [protein]-L-
CC glutamate 5-O-methyl ester + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:24452, Rhea:RHEA-COMP:10208, Rhea:RHEA-COMP:10311,
CC ChEBI:CHEBI:29973, ChEBI:CHEBI:57856, ChEBI:CHEBI:59789,
CC ChEBI:CHEBI:82795; EC=2.1.1.80;
CC Evidence={ECO:0000256|ARBA:ARBA00001541,
CC ECO:0000256|PIRNR:PIRNR000410};
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:MBO0346539.1}.
