WebMar 6, 2024 · ATCase [aspartate transcarbamoylase] catalyzes the first step in pyrimidine biosynthesis. In bacteria pyrimidine nucleotide biosynthesis is regulated by a feedback … WebQ1: What is the effect of CTP on the activity of ATCase? A) It stabilizes the T-state of ATCase and increases the activity of the enzyme B) It stabilizes the T-state of ATCase and decreases the activity of the neyzme C) It stabilizes the R-state of ATCase and increases the activity of the enzyme
WebCTP and ATP are the specific allosteric regulators of this pathway in prokaryotes, and their rate-limiting target enzyme is the phase two-specific ATCase. In this system CTP and ATP are, respectively, inhibitory and stimulatory. View chapter Purchase book Biosynthesis of cell wall teichoic acid polymers WebA) A reaction may not occur at a detectable rate even though it has a favorable equilibrium. B) After a reaction, the enzyme involved becomes available to catalyze the reaction again. C) For S → P, a catalyst shifts the reaction equilibrium to the right. D) Lowering the temperature of a reaction will lower the reaction rate.
WebDuring the allosteric regulation of the bacterial enzyme aspartate transcarbamoylase (ATCase), two different allosteric regulators affect the activity of the enzyme on its substrate aspartate. CTP (cytidine triphosphate) _____ ATCase activity, while ATP (adenosine triphosphate) _____ ATCase activity.
