UniProt functional annotation for Q9STG6

UniProt code: Q9STG6.

Organism: Arabidopsis thaliana (Mouse-ear cress).
Taxonomy: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis.
 
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. {ECO:0000269|PubMed:20227352}.
 
Catalytic activity: Reaction=dUTP + H2O = diphosphate + dUMP + H(+); Xref=Rhea:RHEA:10248, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019, ChEBI:CHEBI:61555, ChEBI:CHEBI:246422; EC=3.6.1.23;
Cofactor: Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 1 Mg(2+) per trimer.;
Pathway: Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2.
Subunit: Homotrimer. {ECO:0000269|PubMed:17565183}.
Miscellaneous: Silencing of DUT leads to high seedling mortality and affects plant growth and flower organ morphology in surviving plants.
Similarity: Belongs to the dUTPase family. {ECO:0000305}.
