Thhe two substrates of this enzyme are D-altronic acid and oxidised nicotinamide adenine dinucleotide (NAD⁺). Its products are D-tagaturonic acid, reduced NADH, and a proton.^[1][2]

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-altronate:NAD⁺ 3-oxidoreductase. Other names in common use include altronic oxidoreductase, altronate oxidoreductase, TagUAR, altronate dehydrogenase, and D-tagaturonate reductase. This enzyme participates in pentose and glucuronate interconversions.
