Function
function
Catalyzes the reductive methylation of 2'-deoxyuridine-5'-monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
Catalytic activity
- dUMP + (6R)-5,10-methylene-5,6,7,8-tetrahydrofolate = 7,8-dihydrofolate + dTMP
Pathway
Pyrimidine metabolism; dTTP biosynthesis.
