| Accepted name: |
kaempferol 3-O-xylosyltransferase |
| Reaction: |
UDP-α-D-xylose + kaempferol = UDP + kaempferol 3-O-β-D-xyloside |

| Other name(s): |
F3XT; UDP-D-xylose:flavonol 3-O-xylosyltransferase; flavonol 3-O-xylosyltransferase |
| Systematic name: |
UDP-α-D-xylose:kaempferol 3-O-D-xylosyltransferase |
| Comments: |
The enzyme from the plant Euonymus alatus also catalyses the 3-O-D-xylosylation of other flavonols (e.g. quercetin, isorhamnetin, rhamnetin, myricetin, fisetin) with lower activity. |
