Taxonomic lineage

cellular organisms › Bacteria › Proteobacteria › Betaproteobacteria › Rhodocyclales › Rhodocyclaceae › Azoarcus

Protein attributes

Sequence length	149 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA By similarity. HAMAP-Rule MF_00116
Catalytic activity	dUTP + H2O = dUMP + diphosphate. HAMAP-Rule MF_00116
Cofactor	Magnesium By similarity.
Pathway	Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2. HAMAP-Rule MF_00116
Sequence similarities	Belongs to the dUTPase family.
