In enzymology, homoisocitrate dehydrogenase (EC 1.1.1.87) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are (-)-homoisocitric acid and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 2-oxoadipic acid, carbon dioxide, reduced NADH, and a proton.
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 (1R,2S)-1-hydroxybutane-1,2,4-tricarboxylate:NAD+ oxidoreductase (decarboxylating). Other names in common use include 2-hydroxy-3-carboxyadipate dehydrogenase, 3-carboxy-2-hydroxyadipate dehydrogenase, homoisocitric dehydrogenase, (−)-1-hydroxy-1,2,4-butanetricarboxylate:NAD+ oxidoreductase, (decarboxylating), 3-carboxy-2-hydroxyadipate:NAD+ oxidoreductase (decarboxylating), and HICDH. This enzyme participates in lysine biosynthesis.
