Methylation of the C-terminal amino group of the enzyme and proteolytic cleavage of the N-terminal amino acid residue resulted in the modification of the protein to a form of lower molecular weight, identical to that of the inactivated enzyme. The major changes observed in the EDTA-modified enzyme were a reduction in thermal stability and a decrease in gel mobility, with the conformation of the protein remaining unchanged.

However, when the molar excess of EDTA exceeded the stoichiometric amount of bound metal ion, the EDTA-modified enzyme conformation differed significantly from that of the native enzyme. When the amount of EDTA added was in the molar range that was associated with the inactivation, protein conformations in native and EDTA-modified enzyme were indistinguishable. Molecular sieve chromatography of the enzyme-EDTA complex resulted in separation of three protein species with the same mobility as the native enzyme, two EDTA-inactivated forms and one EDTA-modified form. The EDTA-modified protein had a lower activity than that of the native enzyme. The inactivation rate followed first-order kinetics with respect to EDTA concentration, indicating that one enzyme subunit is modified by two moles of the chelator. Phosphofructokinase from rabbit muscle was inactivated by EDTA.
