General annotation (Comments)

Function

May function in the production of NADPH for fatty acid and sterol synthesis.

Catalytic activity

Isocitrate + NADP(+) = 2-oxoglutarate + CO(2) + NADPH.

Oxalosuccinate + NADP(+) = 2-oxoglutarate + CO(2) + NADPH.

Cofactor

Binds 1 magnesium or manganese ion per subunit By similarity.

Enzyme regulation

By catabolite repression.

Subunit structure

Homodimer.

Subcellular location

Cytoplasm.

Post-translational modification

The N-terminus is blocked.

Miscellaneous

Present with 2620 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the isocitrate and isopropylmalate dehydrogenases family.
