  • Title: Regulation of citrate synthase activity of Saccharomyces cerevisiae.
    Author: Coleman JS, Bhattacharjee JK.
    Journal: Antonie Van Leeuwenhoek; 1975; 41(3):249-56. PubMed ID: 2100.
    Abstract:
    Citrate synthase activity of Saccharomyces cerevisiae was determined by a radioactive assay procedure and the reaction product, 14C-citric acid, was identified by chromatographic techniques. ATP, d-ATP, GTP and NADH were most inhibitory to the citrate synthase invitro. The activity was inhibited to a lesser extent by ADP, UTP, and NADP whereas, AMP and CTP were much less inhibitory. NADH, like NAD, glutamic acid, glutamine, arginine, ornithine, proline, aspartic acid and alpha-ketoglutarate exhibited no inhibition. These results have been discussed in the light of the role of citrate synthase for the energy metabolism and glutamic acid biosynthesis.
