Name: Isocitrate dehydrogenase kinase/phosphatase
Synonyms:
  • IDH kinase/phosphatase
  • IDHK/P
Gene Name: aceK
Enzyme Class:
Biological Properties
General Function: Involved in [isocitrate dehydrogenase (NADP+)] kinase activity
Specific Function: Bifunctional enzyme which can phosphorylate or dephosphorylate isocitrate dehydrogenase (IDH) on a specific serine residue. This is a regulatory mechanism which enables bacteria to bypass the Krebs cycle via the glyoxylate shunt in response to the source of carbon. When bacteria are grown on glucose, IDH is fully active and unphosphorylated, but when grown on acetate or ethanol, the activity of IDH declines drastically concomitant with its phosphorylation
