CC   -!- FUNCTION: Bifunctional enzyme which can phosphorylate or
CC       dephosphorylate isocitrate dehydrogenase (IDH) on a specific serine
CC       residue. This is a regulatory mechanism which enables bacteria to
CC       bypass the Krebs cycle via the glyoxylate shunt in response to the
CC       source of carbon. When bacteria are grown on glucose, IDH is fully
CC       active and unphosphorylated, but when grown on acetate or ethanol, the
CC       activity of IDH declines drastically concomitant with its
CC       phosphorylation. {ECO:0000255|HAMAP-Rule:MF_00747}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-seryl-[isocitrate dehydrogenase] + ATP = O-phospho-L-seryl-
CC         [isocitrate dehydrogenase] + ADP + H(+); Xref=Rhea:RHEA:43540,

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00747}.
CC   -!- SIMILARITY: Belongs to the AceK family. {ECO:0000255|HAMAP-
