Cat No.
NATE-1108
Description
In enzymology, a D-malate dehydrogenase (decarboxylating) (EC 1.1.1.83) is an enzyme that catalyzes the chemical reaction: (R)-malate + NAD+ ? pyruvate + CO2 + NADH. Thus, the two substrates of this enzyme are (R)-malate and NAD+, whereas its 3 products are pyruvate, CO2, and NADH. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
