IUBMB Enzyme Nomenclature


Accepted name: [isocitrate dehydrogenase (NADP+)] kinase

Reaction: ATP + [isocitrate dehydrogenase (NADP+)] = ADP + [isocitrate dehydrogenase (NADP+)] phosphate

Other name(s): [isocitrate dehydrogenase (NADP)] kinase; ICDH kinase/phosphatase; IDH kinase; IDH kinase/phosphatase; IDH-K/P; IDHK/P; isocitrate dehydrogenase kinase (phosphorylating); isocitrate dehydrogenase kinase/phosphatase; STK3

Systematic name: ATP:[isocitrate dehydrogenase (NADP+)] phosphotransferase

Comments: The enzyme has no activating compound but is specific for its substrate. Phosphorylates and inactivates EC, isocitrate dehydrogenase (NADP+).
