Diiodophenylpyruvate reductase

In enzymology, a diiodophenylpyruvate reductase (EC 1.1.1.96) is an enzyme that catalyzes the chemical reaction

3-(3,5-diiodo-4-hydroxyphenyl)lactate + NAD⁺ ⇌ 3-(3,5-diiodo-4-hydroxyphenyl)pyruvate + NADH + H⁺

Thus, the two substrates of this enzyme are 3-(3,5-diiodo-4-hydroxyphenyl)lactate and NAD⁺, whereas its 3 products are 3-(3,5-diiodo-4-hydroxyphenyl)pyruvate, 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 3-(3,5-diiodo-4-hydroxyphenyl)lactate:NAD⁺ oxidoreductase. Other names in common use include aromatic alpha-keto acid, KAR, and 2-oxo acid reductase.
