Protein attributes

Sequence length729 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

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

Cofactor

Binds 1 magnesium or manganese ion per subunit By similarity.

Enzyme regulation

Weakly inhibited by oxaloacetate, 2-oxoglutarate, and citrate. Severely inhibited by oxaloacetate plus glyoxylate By similarity.

Subunit structure

Monomer By similarity.

Sequence similarities

Belongs to the monomeric-type IDH family.

Sequence caution

The sequence BAC17492.1 differs from that shown. Reason: Erroneous initiation.
