Chlorophenol O-methyltransferase () is an enzyme that catalyzes the chemical reaction
This is a methylation reaction in which 2,4,6-trichlorophenol is converted to 2,4,6-trichloroanisole. The methyl group comes from the cofactor, S-adenosyl methionine (SAM), which becomes S-adenosyl-L-homocysteine (SAH). The enzyme was characterised from the fungal genus Trichoderma.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:trichlorophenol O-methyltransferase. Other names in common use include halogenated phenol O-methyltransferase, trichlorophenol, and O-methyltransferase. It methylates a variety of chlorinated phenols.
