title: Determination of magnesium and potassium binding constants to phosphoenolpyruvate, 2- and 3-phosphoglycerate and a number of other anions.
abstract: The stability constants for the binding of magnesium ions to phosphoenolpyruvate, 2- and 3-phosphoglycerates, 2,3-diphosphoglycerate, Pi, glucose 6-phosphate, isocitrate, glutamate and NAD have been determined spectrophotometrically in the presence of 8-hydroxyquinoline at 25 and 37 degrees C. Estimates of potassium binding constants have also been calculated for phosphoenolpyruvate and 2- and 3-phosphoglycerate and compared with previously published values.
