Short name=TSase
EC=2.1.1.45
Gene names
Name:thyA
Ordered Locus Names:b2827, JW2795
OrganismEscherichia coli (strain K12) [Reference proteome] [HAMAP]
Taxonomic identifier83333 [NCBI]
Taxonomic lineageBacteriaProteobacteriaGammaproteobacteriaEnterobacterialesEnterobacteriaceaeEscherichia

Protein attributes

Sequence length264 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

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. HAMAP-Rule MF_00008

Catalytic activity

5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP. HAMAP-Rule MF_00008

Pathway

Pyrimidine metabolism; dTTP biosynthesis. HAMAP-Rule MF_00008

Subunit structure

Homodimer.

Subcellular location

Cytoplasm HAMAP-Rule MF_00008.

Post-translational modification

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. HAMAP-Rule MF_00008

Sequence similarities

Belongs to the thymidylate synthase family. Bacterial-type ThyA subfamily.
