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. |
