Xylosyltransferase are transferase enzymes which act upon xylose and are classified under EC 2.4.2.[1][2]

More specifically, they can refer to:

xylosyl transferase is the first enzyme involved in the biosynthesis of glycosaminoglycan chains, an important constituent of proteoglycans. There are two types of xylosyl transferases type I and type II.
