Accepted name: 3-O-α-D-mannopyranosyl-α-D-mannopyranose xylosylphosphotransferase
Reaction: UDP-xylose + 3-O-α-D-mannopyranosyl-α-D-mannopyranose = UMP + 3-O-(6-O-α-D-xylosylphospho-α-D-mannopyranosyl)-α-D-mannopyranose
Glossary: O-α-D-xylosylphospho-α-D-mannopyranosyl)-α-D-mannopyranose = O-α-D-xylosylphosphono-α-D-mannopyranosyl)-α-D-mannopyranose
Other name(s): XPT1
Systematic name: UDP-D-xylose:3-O-α-D-mannopyranosyl-α-D-mannopyranose xylosylphosphotransferase
Comments: Mn2+ required for activity. The enzyme is specific for mannose as an acceptor but is flexible as to the structural context of the mannosyl disaccharide.
