Cofactor

Magnesium By similarity. HAMAP-Rule MF_01976

Pathway

Carbohydrate degradation; glycolysis; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose: step 3/4. HAMAP-Rule MF_01976

Subunit structure

Homodimer or homotetramer By similarity. HAMAP-Rule MF_01976

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01976.

Sequence similarities

Belongs to the phosphofructokinase type A (PFKA) family. Mixed-substrate PFK group III subfamily.
