General annotation (Comments)

Function

May supply 2-oxoglutarate for amino acid biosynthesis and ammonia assimilation via the glutamine synthetase/glutamate synthase (GS/GOGAT) pathway By similarity.

Catalytic activity

Isocitrate + NADP+ = 2-oxoglutarate + CO2 + NADPH.

Cofactor

Binds 1 magnesium or manganese ion per subunit By similarity.

Subunit structure

Heterodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the isocitrate and isopropylmalate dehydrogenases family.

Sequence caution

The sequence CAA53300.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
