WebCTP is a known inhibitor in ATCase, The enzyme that catalyzes the first three action in the pathway for the synthesis of this compound. This is an example of Feedback inhibition Homotrophic effects for allosteric enzymes involve The same Molecule binding to different sites in the enzyme WebN-carbamoylaspartate ultimately is converted to the pyrimidine nucleotide cytidine triphosphate (CTP), which is the negative modulator of the enzyme. That is, as the CTP concentration increases, it inhibits the ATCase by decreasing its affinity for substrates. The preceding is an example of an allosteric feedback inhibition. sidney walters
