2.1.1.267 | 4 S-adenosyl-L-methionine + quercetin |
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 |
2.1.1.267 | more |
CROMT2 is involved in biosynthesis of glycosides and anthocyanins |
2.1.1.267 | more |
OMT2 performs two sequential methylations at the 3'-and 5'-positions of the B-ring in myricetin (flavonol) and dihydromyricetin (dihydroflavonol) |
2.1.1.267 | more |
anthocyanin O-methyltransferase methylates anthocyanins of both groups, di- and trihydroxylated anthocyanins, quantitative trait locus analyses for the ratios of tri/di-hydroxylated and methylated/non-methylated anthocyanins using a population from an interspecific hybrid cross, relationship between the genotypes of the markers closest to the major quantitative trait loci and the expression levels of anthocyanin biosynthetic genes, overview |
2.1.1.267 | more |
the enzyme AnthOMT shows a strong affinity for glycosylated anthocyanins, while other flavonoid glycosides and aglycones are much less preferred |
2.1.1.267 | S-adenosyl-L-methionine + 3'-methoxydelphinidin 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 |
