Protein attributes

Sequence length	264 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Provides the sole de novo source of dTMP for DNA biosynthesis. This protein also binds to its mRNA thus repressing its own translation By similarity. HAMAP MF_00008
Catalytic activity	5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP. HAMAP MF_00008
Pathway	Pyrimidine metabolism; dTTP biosynthesis. HAMAP MF_00008
Subunit structure	Homodimer By similarity. HAMAP MF_00008
Subcellular location	Cytoplasm By similarity HAMAP MF_00008.
Post-translational modification	The N-terminal is probably N-(dihydroxymethyl)-methionine, the hydrated form of N-formylmethionine By similarity. HAMAP MF_00008
Sequence similarities	Belongs to the thymidylate synthase family. Bacterial-type ThyA subfamily.
