CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-galactose 1-phosphate + UDP-alpha-D-glucose = alpha-D-
CC glucose 1-phosphate + UDP-alpha-D-galactose; Xref=Rhea:RHEA:13989,
CC ChEBI:CHEBI:58336, ChEBI:CHEBI:58601, ChEBI:CHEBI:58885,
CC ChEBI:CHEBI:66914; EC=2.7.7.12;
CC Evidence={ECO:0000250|UniProtKB:P09148};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000250|UniProtKB:P09148};
CC Note=Binds 1 zinc ion per subunit. Zinc binding seems to play a
CC structural role. {ECO:0000250|UniProtKB:P09148};
CC -!- PATHWAY: Carbohydrate metabolism; galactose metabolism.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P07902}.
CC -!- SIMILARITY: Belongs to the galactose-1-phosphate uridylyltransferase
CC type 1 family. {ECO:0000305}.
