General annotation (Comments)

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 By similarity. HAMAP MF_00747
Catalytic activity	ATP + [isocitrate dehydrogenase (NADP+)] = ADP + [isocitrate dehydrogenase (NADP+)] phosphate. HAMAP MF_00747
Subcellular location	Cytoplasm By similarity HAMAP MF_00747.
Sequence similarities	Belongs to the aceK family.
