n. (context enzyme English) Any glycosyltransferase that catalyzes the transfer of 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.
