Ec Number:2.7.8.32

3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase (XPT1) is an enzyme with systematic name UDP-D-xylose:3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase.[1] This enzyme catalyses the following chemical reaction

UDP-xylose + 3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose

\rightleftharpoons

UMP + 3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-alpha-D-mannopyranose

Mn2+ required for activity.
