In [[Biology:Enzymology|enzymology]], a '''zeatin O-beta-D-xylosyltransferase''' ({{EC number|2.4.2.40}}) is an [[Biology:Enzyme|enzyme]] that [[Chemistry:Catalysis|catalyzes]] the [[Chemistry:Chemical reaction|chemical reaction]]

:UDP-D-xylose + zeatin <math>\rightleftharpoons</math> UDP + O-beta-D-xylosylzeatin

Thus, the two [[Biology:Substrate (biochemistry)|substrates]] of this enzyme are UDP-D-xylose and [[Chemistry:Zeatin|zeatin]], whereas its two [[Chemistry:Product|products]] are [[Chemistry:Uridine diphosphate|UDP]] and O-beta-D-xylosylzeatin.

This enzyme belongs to the family of [[Biology:Glycosyltransferase|glycosyltransferase]]s, specifically the pentosyltransferases.  The [[Biology:List of enzymes|systematic name]] of this enzyme class is '''UDP-D-xylose:zeatin O-beta-D-xylosyltransferase'''. Other names in common use include '''uridine diphosphoxylose-zeatin xylosyltransferase''', and '''zeatin O-xylosyltransferase'''.
