Protein

Deoxyuridine 5'-triphosphate nucleotidohydrolase

Gene

dut

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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

Catalytic activityi

dUTP + H2O = dUMP + diphosphate.

Cofactori

Mg2+By similarity

Pathwayi: dUMP biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes dUMP from dCTP (dUTP route).
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Deoxyuridine 5'-triphosphate nucleotidohydrolase (dut)
This subpathway is part of the pathway dUMP biosynthesis, which is itself part of Pyrimidine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes dUMP from dCTP (dUTP route), the pathway dUMP biosynthesis and in Pyrimidine metabolism.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
