Protein attributes

Sequence length	264 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
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.
Catalytic activity	5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.
Pathway	Pyrimidine metabolism; dTTP biosynthesis.
Subunit structure	Homodimer By similarity.
Subcellular location	CytoplasmBy similarity.
Post-translational modification	The N-terminus is carboxylated By similarity.
Sequence similarities	Belongs to the thymidylate synthase family.
