CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03184};
CC -!- ACTIVITY REGULATION: Allosterically activated by ADP, AMP, or fructose
CC 2,6-bisphosphate, and allosterically inhibited by ATP or citrate.
CC {ECO:0000255|HAMAP-Rule:MF_03184}.
CC -!- PATHWAY: Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-
CC phosphate and glycerone phosphate from D-glucose: step 3/4.
CC {ECO:0000255|HAMAP-Rule:MF_03184}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_03184}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03184}.
CC -!- SIMILARITY: Belongs to the phosphofructokinase type A (PFKA) family.
CC ATP-dependent PFK group I subfamily. Eukaryotic two domain clade 'E'
CC sub-subfamily. {ECO:0000255|HAMAP-Rule:MF_03184}.
