General annotation (Comments)

Catalytic activity

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

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

Cofactor

Binds 1 magnesium or manganese ion per subunit By similarity.

Subunit structure

Homodimer. Ref.5

Miscellaneous

The enzyme can be phosphorylated in vitro by the E.coli isocitrate dehydrogenase kinase/phosphatase, but B.subtilis lacks such an enzyme.

Sequence similarities

Belongs to the isocitrate and isopropylmalate dehydrogenases family.
