Pantoate 4-dehydrogenase

Template:Infobox enzyme In enzymology, a pantoate 4-dehydrogenase (Template:EC number) is an enzyme that catalyzes the chemical reaction

(R)-pantoate + NAD⁺ $\rightleftharpoons$ (R)-4-dehydropantoate + NADH + H⁺

Thus, the two substrates of this enzyme are (R)-pantoate and NAD⁺, whereas its 3 products are (R)-4-dehydropantoate, 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 (R)-pantoate:NAD⁺ 4-oxidoreductase. Other names in common use include pantoate dehydrogenase, pantothenase, and D-pantoate:NAD⁺ 4-oxidoreductase. This enzyme participates in pantothenate and coa biosynthesis.
