the changes in the rate of inactivation in the presence of substrates and mn2+ were used to determine the dissociation constants for enzyme-ligand complexes , and values of 23 +/- 3 microm , 168 +/- 44 microm and 244 +/- 54 microm were found for the dissociation constants for the enzyme-mn2+ , enzyme-adp and enzyme-phosphoenolpyruvate complexes , respectively .
