- D-galactose + NADP+ D-galactono-1,5-lactone + NADPH + H+
Thus, the two substrates of this enzyme are D-galactose and NADP+, whereas its 3 products are D-galactono-1,5-lactone, 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 D-galactose:NADP+ 1-oxidoreductase. Other names in common use include D-galactose dehydrogenase (NADP+), and galactose 1-dehydrogenase (NADP+). This enzyme participates in galactose metabolism.
