Protein

Thymidylate synthase

Gene

thyA

Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Provides the sole de novo source of dTMP for DNA biosynthesis. This protein also binds to its mRNA thus repressing its own translation.

Catalytic activityi

5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.UniRule annotation

Post-translational modificationi

Although not discussed in the published references, Met-1 is represented in the submitted PDB entries as being modified by either a formyl, or a carboxyl group. The N-terminal is probably N-(dihydroxymethyl)methionine, the hydrated form of N-formylmethionine.
