3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase (EC 2.7.8.32 XPT1) is an enzyme with system name UDP-D-xylose:3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase. This enzyme catalyses the following chemical reaction UDP-xylose + 3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose UMP + 3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-alpha-D-mannopyranoseMn2+ required for activity.
