(R)-dehydropantoate dehydrogenase

In enzymology, a (R)-dehydropantoate dehydrogenase (EC number|1.2.1.33) is an enzyme that catalyzes the chemical reaction

:(R)-4-dehydropantoate + NAD⁺ + H₂O $ightleftharpoons$ (R)-3,3-dimethylmalate + NADH + 2 H⁺

The 3 substrates of this enzyme are (R)-4-dehydropantoate, NAD⁺, and H₂O, whereas its 3 products are (R)-3,3-dimethylmalate, NADH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (R)-4-dehydropantoate:NAD+ 4-oxidoreductase. Other names in common use include D-aldopantoate dehydrogenase, D-2-hydroxy-3,3-dimethyl-3-formylpropionate:diphosphopyridine, and nucleotide (DPN+) oxidoreductase. This enzyme participates in pantothenate and coa biosynthesis.
