General annotation (Comments)

Function	Catalyzes the NAD⁺-dependent conversion of homoisocitrate to alpha-ketoadipate. Ref.4
Catalytic activity	(1R,2S)-1-hydroxybutane-1,2,4-tricarboxylate + NAD⁺ = 2-oxoadipate + CO₂ + NADH. Ref.4
Cofactor	Binds 1 magnesium or manganese ion per subunit By similarity.
Enzyme regulation	Activity is repressed 4-fold by lysine. Ref.6
Pathway	Amino-acid biosynthesis; L-lysine biosynthesis via AAA pathway; L-alpha-aminoadipate from 2-oxoglutarate: step 3/4.
Subcellular location	Mitochondrion Ref.8 Ref.10.
Miscellaneous	Present with 19079 molecules/cell in log phase SD medium. Ref.9
Sequence similarities	Belongs to the isocitrate and isopropylmalate dehydrogenases family.
Biophysicochemical properties	Kinetic parameters: The KM for homoisocitrate is lower than 10 µM. K_M=1.5 mM for 2-oxoadipate Ref.5 K_M=330 µM for NAD⁺ K_M=65 µM for NADH pH dependence: Optimum pH is 8.3-8.8 for the forward reaction, and 7 for the reverse reaction.
