EC=2.1.1.80

Gene names

Name:	cheR
Ordered Locus Names:	BSU22720

Organism

Bacillus subtilis

Taxonomic identifier

1423 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	256 AA.
Sequence status	Complete.
Protein existence	Predicted

General annotation (Comments)

Function	Methylation of the membrane-bound methyl-accepting chemotaxis proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP. CheR is responsible for the chemotactic adaptation to repellents.
Catalytic activity	S-adenosyl-L-methionine + protein L-glutamate = S-adenosyl-L-homocysteine + protein L-glutamate methyl ester.
Subunit structure	Monomer.
Sequence similarities	Contains 1 cheR-type methyltransferase domain.
