CC -!- FUNCTION: Catalyzes the formation of UDP-glucuronic acid which is
CC required for capsular hyaluronic acid synthesis. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + 2 NAD(+) + UDP-alpha-D-glucose = 3 H(+) + 2 NADH + UDP-
CC alpha-D-glucuronate; Xref=Rhea:RHEA:23596, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:58052, ChEBI:CHEBI:58885; EC=1.1.1.22;
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-alpha-D-glucuronate
CC biosynthesis; UDP-alpha-D-glucuronate from UDP-alpha-D-glucose: step
CC 1/1.
CC -!- SIMILARITY: Belongs to the UDP-glucose/GDP-mannose dehydrogenase
CC family. {ECO:0000305}.
