CC -!- FUNCTION: Xylosylphosphotransferase that is specific for UDP-xylose as
CC a donor and mannose as an acceptor to form a xylose-alpha-1-phosphate-
CC 6-mannose linkage. Functions in the O-glycosylation of proteins en
CC route through the secretory pathway (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-alpha-D-mannopyranosyl-alpha-D-mannopyranose + UDP-alpha-D-
CC xylose = 3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-
CC alpha-D-mannopyranose + H(+) + UMP; Xref=Rhea:RHEA:28262,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57632, ChEBI:CHEBI:57865,
CC ChEBI:CHEBI:61663, ChEBI:CHEBI:61665; EC=2.7.8.32;
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane {ECO:0000250}; Single-
CC pass type I membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the XPT1 family. {ECO:0000305}.
