Display the word mapDisplay the reaction diagram Show all sequences 1.14.20.5more domain swapping experiments joining the N-terminus of flavanone 3beta-hydroxylase with the C-terminus of flavone synthase I and vice versa. Conversion of seven active site residues of flavanone 3beta-hydroxylase into the corresponding amino acids of flavone synthase I causes a nearly complete change in enzyme activity from flavanone 3beta-hydroxylase to flavone synthase I 689577

Display the word mapDisplay the reaction diagram Show all sequences 1.14.20.5more transgenic seedlings of Arabidopsis thaliana accumulate substantial amounts of apigenin, and the apigenin level correlates with the abundance of enzyme mRNA 685694
Display the word mapDisplay the reaction diagram Show all sequences 1.14.20.5more use of enzyme for construction of a system for producing unnatural flavonoids and stilbenes in Escherichia coli by expression of the respective genes on three plasmids. Incubation of the recombinant Escherichia coli with exogenously supplied carboxylic acids leads to production of 87 different polyketides, including 36 unnatural flavonoids and stilbenes 679173
Display the word mapDisplay the reaction diagram Show all sequences 1.14.20.5Y240P the mutant enzyme converts naringenin to apigenin without producing any 2-hydroxynaringenin. The mutant has a higher affinity (lower Km) with naringenin than the wild type enzyme, but the catalytic efficiency of the mutant is lower than that of wild type enzyme. The mutant enzyme is able to oxidize dihydrokaempferol to kaempferol with 104% of the catalytic activity relative to wild-type enzyme 742512
Display the word mapDisplay the reaction diagram Show all sequences 1.14.20.5Y240P/A120M the enzyme activity of the double mutant is reduced to a level of about 10% of the activity of the wild type enzyme and the only product generated is apigenin. The mutant enzyme is able to oxidize dihydrokaempferol to kaempferol with 175% of the catalytic activity relative to wild-type enzyme 742512
