6-phosphofructo-2-kinase/fructose-2,6-biphosphatase complex 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 1 complex 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 2 complex 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 complex 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 4 complex A homodimeric, bifunctional enzyme complex which catalyzes the synthesis and degradation of fructose 2,6-bisphosphate, and is required for both glycolysis and gluconeogenesis. GO:0043540 Note that we use this single class to represent all 4 isoforms of this complex. We decided to do this because the isoforms do not differ in function, rather in expression and regulation. We may want to revisit this in future. cellular_component go.owl pro.owl cytosolic part transferase complex, transferring phosphorus-containing groups
