In enzymology a zeatin O-beta-D-xylosyltransferase (EC 2.4.2.40) is an enzyme that catalyzes the chemical reactionUDP-D-xylose + zeatin UDP + O-beta-D-xylosylzeatinThus the two substrates of this enzyme are UDP-D-xylose and zeatin whereas its two products are UDP and O-beta-D-xylosylzeatin.This enzyme belongs to the family of glycosyltransferases specifically the pentosyltransferases. The systematic name of this enzyme class is UDP-D-xylose:zeatin O-beta-D-xylosyltransferase.
