Comments

FUNCTION: Performs an essential role in the oxidative function of the citric acid cycle (By similarity).
CATALYTIC ACTIVITY: Isocitrate + NAD⁺ = 2-oxoglutarate + CO₂ + NADH.
COFACTOR: Binds 1 magnesium or manganese ion per subunit.
SUBUNIT: Octamer of two non-identical subunits IDH1 and IDH2 (By similarity).
SUBCELLULAR LOCATION: Mitochondrion (By similarity).
SIMILARITY: Belongs to the isocitrate and isopropylmalate dehydrogenases family.
