Probably transfers a methyl group from the S-adenosylmethionine (SAM) cofactor and, subsequently or simultaneously, a water molecule onto the double bound of ethylene substrates, leading to the formation of the hydroxylated product at the distal position. Involved in the activation of the antitubercular drug thiacetazone (TAC).<ref>PMID:10844652</ref> <ref>PMID:12473649</ref> | ||
