The 3 substrates of this enzyme are D-galacturonate, NAD+, and H2O, whereas its 3 products are D-galactaro-1,5-lactone (the lactone of D-galactarate), NADH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is uronate:NAD+ 1-oxidoreductase. Other names in common use include uronate: NAD-oxidoreductase, and uronic acid dehydrogenase.
