4 S-adenosyl-L-methionine + quercetin
4 S-adenosyl-L-homocysteine + 3,3',5,7-tetramethoxyquercetin
whole-cell biocatalysis using CdFOMT5 expressed in Escherichia coli cells is performed using quercetin as a substrate, and 3,3',5,7-tetramethylated quercetin is obtained as the final product

S-adenosyl-L-methionine + 3'-methoxydelphinidin 3-O-glucoside
S-adenosyl-L-homocysteine + 3',5'-dimethoxydelphinidin 3-O-glucoside
very low activity, with delphinidin 3-O-glucoside as substrate, NmAMT6 almost exclusively yields petunidin 3-O-glucoside rather than malvidin 3-O-glucoside. This specificity is consistent with the anthocyanin composition of Nemophila petals
