In enzymology, a galactitol-1-phosphate 5-dehydrogenase (EC 1.1.1.251) is an enzyme that catalyzes the chemical reaction

galactitol-1-phosphate + NAD+ L-tagatose 6-phosphate + NADH + H+

Thus, the two substrates of this enzyme are galactitol-1-phosphate and NAD+, whereas its 3 products are L-tagatose 6-phosphate, 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 galactitol-1-phosphate:NAD+ oxidoreductase. This enzyme participates in galactose metabolism. It employs one cofactor, zinc.

Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism. Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine nucleobase and the other, nicotinamide. NAD exists in two forms: an oxidized and reduced form, abbreviated as NAD+ and NADH (H for hydrogen), respectively.

In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor. This group of enzymes usually utilizes NADP+ or NAD+ as cofactors. Transmembrane oxidoreductases create electron transport chains in bacteria, chloroplasts and mitochondria, including respiratory complexes I, II and III. Some others can associate with biological membranes as peripheral membrane proteins or be anchored to the membranes through a single transmembrane helix.
