S-adenosyl-L-methionine (AdoMet)-dependent O-methyltransferases (OMTs) catalyze the transmethylation of a variety of phenolics in bacteria, plants, and humans. To rapidly characterize phenolic OMT activities, we adapted Gibbs' reagent, the dye originally used for detecting phenols, to develop a convenient assay method
