Xylose

Xylosyltransferase are transferase enzymes which act upon xylose and are classified under EC 2.4.2.

More specifically, they can refer to:

• Dolichyl-phosphate D-xylosyltransferase
• Dolichyl-xylosyl-phosphate-protein xylosyltransferase
• Flavonol-3-O-glycoside xylosyltransferase
• Glycoprotein 2-beta-D-xylosyltransferase
• Protein xylosyltransferase
• Xyloglucan 6-xylosyltransferase
• XYLT1
• XYLT2
• Zeatin O-beta-D-xylosyltransferase

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.
