2.4.1.373 additional information expression of truncated forms of enzyme containing either catalytic domain CD1 or CD2. Enzymes devoid of CD2 synthesize products containing only alpha-1,6 linkages. Enzymes devoid of CD1 modified alpha-1,6 linear oligosaccharides and dextran acceptors through the formation of alpha-1,2 linkages 754002 2.4.1.373 W2135F mutant displays 3-4fold improved activity with naringenin 752238 2.4.1.373 W2135G mutant displays 3-4fold improved activity with naringenin 752238 2.4.1.373 W2135G mutant synthesizes four times more morin glucoside than the wild-type 752238 2.4.1.373 W2135I/F2136Y mutant displays 3-4fold improved activity with naringenin, about 60% conversion. Mutant converts nearly 3-times more naringenin than luteolin (59% and 17%, conversion, respectively) 752238 2.4.1.373 W2135L-F2136L mutant significantly synthesizes quercetin di-glucoside 752238 2.4.1.373 W2135V mutant displays 3-4fold improved activity with naringenin 752238
