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 additional information CROMT2 is involved in biosynthesis of glycosides and anthocyanins 2.1.1.267 additional information 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 additional information 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 additional information 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 2.1.1.267 S-adenosyl-L-methionine + a 3'-hydroxyflavonoid - 2.1.1.267 S-adenosyl-L-methionine + cyanidin 3-O-beta-D-glucoside - 2.1.1.267 S-adenosyl-L-methionine + delphinidin 3-O-glucoside - 2.1.1.267 S-adenosyl-L-methionine + delphinidin 3-O-glucoside 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
