Homoisocitrate dehydrogenase


In enzymology, a homoisocitrate dehydrogenase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are -1-hydroxybutane-1,2,4-tricarboxylate and NAD+, whereas its 4 products are 2-oxoadipate, CO2, 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 -1-hydroxybutane-1,2,4-tricarboxylate:NAD+ oxidoreductase . 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, , 3-carboxy-2-hydroxyadipate:NAD+ oxidoreductase , and HICDH. This enzyme participates in lysine biosynthesis.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code.
