The 3 substrates of this enzyme are dTDP-D-galactose, NADP+, and H2O, whereas its 3 products are dTDP-D-galacturonate, NADPH, 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 dTDP-D-galactose:NADP+ 6-oxidoreductase. This enzyme is also called thymidine-diphosphate-galactose dehydrogenase. This enzyme participates in nucleotide sugars metabolism.
