WebDe novo synthesis of thymidylic acid (TMP) occurs exclusively by methylation of the C-5 of dUMP ( Figure 25.18) by thymidylate synthase. The methylene group of N 5 ,N 10 -methylene FH 4 is the source of the methyl group, and FH 4 is oxidized to FH 2. For sustained synthesis, FH 4 must be regenerated by dihydrafolate reductase.
