The plastid isoenzyme of phosphofructokinase from developing castor seeds was stimulated by low conc. of fructose 2,6-diphosphate at pH 7.0. The plastid isoenzyme was unaffected by fructose 2,6-diphosphate at pH 8.0, and the cytosolic isoenzyme was unaffected at pH 7.0 or 8.0. Fructose 2,6-diphosphate and the other regulators of castor phosphofructokinases did not interact.
