Control of CO(2) Fixation by Cell-free Extracts of Chlamydomonas reinhardtii.
Contrary to earlier reports, CO(2) fixation by extracts of Chlamydomonas is inhibited by glutamate and aspartate. These amino acids and some organic acids are shown to be inhibitors of phosphoenolpyruvate carboxylase. Inorganic phosphate is shown to activate CO(2) fixation, but there is a time lag before inorganic phosphate exerts its full activating effect.
