The invention provides for a process for biosynthesis of an O-methylated compound by biotransforming a compound of Formula I into an O-methylated compound, wherein R1 is H, CHO, COOH, C1-6alkyl-COOH, or C2-6 alkenyl-COOH; R2 is H, OH, or OCH3; which process comprises the steps: a) providing a recombinant host cell comprising i) at least one first heterologous gene encoding a first enzyme which is a 4-O-1 methyltransferase operable to biotransform the compound into a 4-O-methylated compound; and ii) optionally, if R2 is OH, at least one second heterologous gene encoding a second enzyme which is a 3-O-methyltransferase, wherein said first and second enzymes are operable to biotransform the compound into a 3,4-O-dimethylated compound; b) cultivating said host cell to express said first and optionally said second enzyme; c) providing the compound and biotransforming the compound into a 4-O-methylated compound or if R2 is OH, into a 3,4-O-dimethylated compound.
