Protein attributes

Sequence length	166 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

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, preventing uracil incorporation into DNA. Ref.4
Catalytic activity	dUTP + H2O = dUMP + diphosphate.
Cofactor	Binds 1 magnesium per trimer.
Pathway	Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2.
Subunit structure	Homotrimer. Ref.5
Miscellaneous	Silencing of DUT leads to high seedling mortality and affects plant growth and flower organ morphology in surviving plants.
Sequence similarities	Belongs to the dUTPase family.
