Protein

Isocitrate dehydrogenase [NADP], mitochondrial

Gene

IDP1

Organism
Candida tropicalis (Yeast)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Mitochondrial IDP1 may regulate flux through the tricarboxylic acid cycle and respiration. Its probably critical function is the production of NADPH.

Catalytic activityi

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

Cofactori

Mg2+By similarity, Mn2+By similarityNote: Binds 1 Mg(2+) or Mn(2+) ion per subunit.By similarity
