Enzyme Information
| 2.1.1.148 |
Thymidylate synthase (FAD).
based on mapping to UniProt Q9WYT0
5,10-methylenetetrahydrofolate + dUMP + NADPH = dTMP + tetrahydrofolate + NADP(+).
-!- Contains FAD. -!- All thymidylate synthases catalyze a reductive methylation involving the transfer of the methylene group of 5,10-methylenetetrahydrofolate to the C5-position of dUMP and a two electron reduction of the methylene group to a methyl group. -!- Unlike the classical thymidylate synthase, ThyA (EC 2.1.1.45), which uses folate as both a 1-carbon donor and a source of reducing equivalents, this enzyme uses a flavin coenzyme as a source of reducing equivalents, which are derived from NADPH.
