Web10 apr. 2024 · Views today: 5.74k. An antimetabolite is a substance that prevents the usage of a metabolite, which is a molecule that occurs naturally in the body's metabolism. Antimetabolites are often structurally identical to the metabolite they interfere with, such as antifolates, which interfere with the usage of folic acid. WebThe enzyme, glu-tamine:phosphoribosylpyrophosphate amidotransferase, is inhibited by the purine 5 -nucleotides AMP and guanosine monophosphate ( [GMP] also called guanylate), the end products of the pathway. The rate of the reaction is also controlled by the intracellular concentration of PRPP.
