Glycyrrhiza inflata O-methyltransferases characterization for one-step production of trimethyl myricetin/dihydromyricetin.
This study expands the enzymatic repertoire of licorice OMTs, provides new insights into the structure-function relationships underling multiple methylations, and establishes a foundation or sustainable biocatalytic production of highly bioactive methylated flavonoids in G. inflata and related species.
