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.

KM=1.5 mM for 2-oxoadipate Ref.5

KM=330 µM for NAD+

KM=65 µM for NADH

pH dependence:

Optimum pH is 8.3-8.8 for the forward reaction, and 7 for the reverse reaction.
