Final answer:
The carbon donor for the formation of TMP from dUMP is 5,10-methylenetetrahydrofolate, and the reaction is catalyzed by the enzyme thymidylate synthase.
Step-by-step explanation:
The carrier that donates a carbon to form thymidine monophosphate (TMP) from deoxyuridine monophosphate (dUMP) is 5,10-methylenetetrahydrofolate. The enzyme that catalyzes this reaction is called thymidylate synthase. During this process, the methylene group of 5,10-methylenetetrahydrofolate is used to methylate dUMP, resulting in the production of TMP and dihydrofolate.
A key aspect of this reaction is the reduction of the methylene group to a methyl group, which is simultaneously added to the uracil base of dUMP to form TMP. The subsequent regeneration of tetrahydrofolate from dihydrofolate is accomplished by the enzyme dihydrofolate reductase, which is another essential step in folate metabolism and nucleotide synthesis.
The carrier that donates a carbon to form TMP from dUMP is Thiamine pyrophosphate (TPP)
The enzyme that catalyzes the reaction is transketolase
For example:
The carbon from dUMP is transferred to TPP, forming TMP
This reaction is catalyzed by the enzyme transketolase
