DE   kaempferol 3-O-xylosyltransferase.
AN   flavonol 3-O-xylosyltransferase.
CA   kaempferol + UDP-alpha-D-xylose = H(+) + kaempferol 3-O-beta-D-xyloside +
CA   UDP.
CC   -!- The enzyme from the plant Euonymus alatus also catalyzes the 3-O-
CC       D-xylosylation of other flavonols (e.g. quercetin, isorhamnetin,
CC       rhamnetin, myricetin, fisetin) with lower activity.
