Abstract:
The carboxylation of phosphoenolpyruvate, catalyzed by a partially purified enzyme extracted from Euglena gracilis cells, is inhibited by intermediates of the tricarboxylic acid cycle and by 3-phosphoglycerate. The presence of two PEP-carboxylating protein fractions which could be separated by ion exchange chromatography was demonstrated. It was found that they differ in apparent Km with respect to CO32- and PEP, and are differently affected by the tricarboxylic acid cycle intermediates and 3-PGA.A comparison of the enzyme obtained from dark-grown cells and green (light-grown) cells indicates that one fraction is present at a relatively higher activity in green cells (Fraction A) while the other is more active in dark-grown cells (Fraction B). © 1974 COPYRIGHT, 1974 BY THE JOURNAL OF BIOCHEMISTRY.
