Name
3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase;
XPT1
Class
Transferases;
Transferring phosphorus-containing groups;
Transferases for other substituted phosphate groups
Sysname
UDP-D-xylose:3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose xylosylphosphotransferase
Reaction(IUBMB)
UDP-xylose + 3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose = UMP + 3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-alpha-D-mannopyranose [RN:R09642]
Reaction(KEGG)
R09642
Substrate
UDP-xylose [CPD:C00190];
3-O-alpha-D-mannopyranosyl-alpha-D-mannopyranose [CPD:C19773]
Product
UMP [CPD:C00105];
3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-alpha-D-mannopyranose [CPD:C19774]
Comment
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.
