Question

Question of Map Complete the reaction for the biosynthesis of thymidine monophosphate (d TMP) from the substrate and the coenzyme 5 N -methylenetetrahydrofolate (5,10-methylene-THF). Note: Not all terms will be used. 5,10-Methylene-THF d'TMP dihydrofolate dUTP dCMP dUMP tetrahydrofolate Select the three true statements. The enzyme that catalyzes this reaction is a target for the treatment of cancer. 5,10-methylene-THF must be regenerated from DHF in order to continue to produce The sole purpose of 5.10-methylene-THF is to donate hydrogen atoms. O This reaction is catalyzed by thymidylate synthase. This reaction is part of all three salvage synthesis pathways of dTTP

Explanation / Answer

Ans: deoxyuridylate (dUMP) + 5,10-Methylene-THF ----> dTMP + dihydrofolate

In this sysnthesis, deoxyuridylate (dUMP) is methylated to deoxythymidylate (dTMP), The methyl donor in this reaction is 5,10-methylenetetrahydrofolate.

True statments:

1. The enzyme that catalyzes this reaction is a target for treatment of cancer.

2. 5,10-methylene-THF must be regenerated from DHF in order to continue to produce dTMP.

3. This reaction is catalyzed by thymidylate synthase
