FunFam 1: Flavin-dependent thymidylate synthase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Thymidylate synthase (FAD). [EC: 2.1.1.148]
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.
