Citrat synthese
WebSimilarly, citrate synthase is not allosterically regulated either, the rate is controlled by concentration of substrate and product, oxaloacetate and citrate respectively. However, isocitrate dehydrogenase is an allosterically regulated enzyme and is considered one of the rate limiting step for the TCA cycle. It show cooperative binding when ... WebNov 23, 2024 · The availability of substrates and products regulates the activity of citrate synthase. For instance, citrate itself acts as an inhibitor for citrate synthase, while oxaloacetate’s binding to it increases its affinity for acetyl-CoA. It bears mention that phosphofructokinase-1 in glycolysis is inhibited by citrate, while it activates acetyl ...
