WebThe transition state of a catalyzed reaction is Lower in energy than that of an uncatalyzed reaction Which trans-membrane signaling receptor activates signaling pathways by usually forming molecular dimers that result in protein phosphorylation? Receptor tyrosine kinase When a cell receives a message, the three stages of cell signaling are: WebCTP 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. feedback inhibition. Homotropic effects for allosteric enzymes involve. the same molecule binding to different sites in the enzyme.
WebThe inhibition of ATCase by CTP is an example of feedback inhibition, the inhibition of an enzyme by the end product of the pathway. Feedback inhibition by CTP ensures that N- carbamoylaspartate and subsequent intermediates in the pathway are not needlessly formed when pyrimidines are abundant.

The allosteric site in the allosteric domain of the R chains of the ATCase complex binds to the nucleotides ATP, CTP and/or UTP. There is one site with high affinity for ATP and CTP and one with 10- to 20-fold lower affinity for these nucleotides in each regulatory dimer. ATP binds predominantly to the high-affinity sites and subsequently activates the enzyme, while UTP and CTP binding leads to inhibition of activity. UTP can bind to the allosteric site, but inhibition of AT…
