WebThe end product metabolism, CTP inhibits ATCase reaction allosterically. The activator ATP competes to the same site at which CTP binds; but the results are diﬀerent. While ATP enhances the aﬃnity of ATCase for its substrates; CTP decreases the aﬃnity. Allosteric eﬀects of ATCase can WebEarly studies found that Escherichia coli ATCase is regulated by the level of CTP, a nucleotide with a pyrimidine ring. Based on biochemical data, researchers proposed a model with two states: a “tense” T state that is inactive, and a …

WebHow is ATCase inhibited? The end product of the pathway CTP inhibits ATCase, this is called feedback inhibition. CTP binds onto an allosteric site of the ATCase What is ATCase made up of? 2 catalytic trimers (for a total of 6 catalytic subunits) 3 regulatory dimers (for a total of 6 regulatory units) WebThe inhibitor CTP binds preferentially to the ___ state of ATCase t The metabolic significance of the activation of ATCase by __________ is that it tends to coordinate the rates of synthesis of purines and pyrimidines.

CTP is a known inhibitor of ATCase, the enzyme that catalyzes the first reaction in the pathway for the synthesis of this compound. This is an example of B. feedback inhibition B. FEEDBACK INHIBITION 4. With CTP present, UTP binding is enhanced and preferentially directed to the low-affinity sites. On the converse, UTP binding leads to enhanced affinity for CTP at the high-affinity sites and together they inhibit enzyme activity by up to 95%, while CTP binding alone inhibits activity to 50% to 70%.
