WebThe specific activity of ATCase was determined for each condition. Generally, a direct correlation was found: at high nucleotide (UTP) concentrations, maximal repression of … WebCTP is also one of the final products of the synthesis reaction chain, and if CTP or UTP is too low compared to ATP, then the activity of ATCase is increased to compensate. Activity of the ATCase is regulated by shifting the enzyme from a tense, low-affinity state to a relaxed, high-affinity state.

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. 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

For nearly 60 years, the ATP activation and the CTP inhibition of Escherichia coli aspartate transcarbamoylase (ATCase) has been the textbook example of allosteric regulation. We present kinetic data and five X-ray structures determined in the absence and presence of a Mg (2+) concentration within the physiological range.
