+ CO2 + NADH
 

The two substrates of this enzyme are (R)-3,3-dimethylmalic acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are α-ketoisovaleric acid, carbon dioxide, 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 (R)-3,3-dimethylmalate:NAD+ oxidoreductase (decarboxylating). This enzyme is also called beta,beta-dimethylmalate dehydrogenase. This enzyme participates in pantothenate and coa biosynthesis. It has 5 cofactors: ammonia, manganese, cobalt, potassium, and NH4+.
