CC -!- FUNCTION: Involved in the metabolism of galactose. Catalyzes the
CC conversion of UDP-galactose (UDP-Gal) to UDP-glucose (UDP-Glc) through
CC a mechanism involving the transient reduction of NAD (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=UDP-alpha-D-glucose = UDP-alpha-D-galactose;
CC Xref=Rhea:RHEA:22168, ChEBI:CHEBI:58885, ChEBI:CHEBI:66914;
CC EC=5.1.3.2;
CC -!- COFACTOR:
CC Name=NAD(+); Xref=ChEBI:CHEBI:57540; Evidence={ECO:0000250};
CC -!- PATHWAY: Carbohydrate metabolism; galactose metabolism.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the NAD(P)-dependent epimerase/dehydratase
CC family. {ECO:0000305}.
