6NN4, 6NN5, 6NN7, 6NN8 - PubMed Abstract: 
Human liver pyruvate kinase (hLPYK) converts phosphoenolpyruvate to pyruvate in the final step of glycolysis. hLPYK is allosterically activated by fructose-1,6-bisphosphate (Fru-1,6-BP). The allosteric site, as defined by previous structural studies, is located in domain C between the phosphate-binding loop (residues 444-449) and the allosteric loop (residues 527-533) ...
