    Pyruvate kinase (PK) plays a major role in the regulation of glycolysis. Its catalytic activity is controlled by the substrate phosphoenolpyruvate and by one or more allosteric effectors. The crystal structures of the non-allosteric PKs from cat and rabbit muscle are known. We have determined the three-dimensional structure of the allosteric type I PK from Escherichia coli, in order to study the mechanism of allosteric regulation.
