Activity summary

The enzyme deoxyuridine triphosphatese also known as dUTPase hydrolyzes dUTP to dUMP and inorganic pyrophosphate. It prevents the incorporation of uracil into DNA which can lead to mutations. The molecular mass of human dUTPase is about 18-20 kDa. It is widely expressed in both prokaryotic and eukaryotic cells including places like the thymus and spleen where DNA synthesis is very active. Alternative names such as DUT or dUTP pyrophosphatase are often used to refer to this enzyme.

Biological function summary

DUTPase maintains nucleotide pool balance and genome integrity. By converting dUTP to dUMP it provides substrates for thymidylate synthase to produce thymidine triphosphate (dTTP) which is essential for DNA replication and repair. dUTPase is not typically part of a larger protein complex but cooperates with other enzymes in nucleotide metabolism. Its activity protects cells from apoptosis that might occur due to extensive uracil misincorporation.

Pathways

DUTPase plays a role in nucleotide metabolism and one-carbon metabolism pathways. It regulates the pyrimidine metabolism pathway ensuring sufficient dTTP levels for DNA synthesis. dUTPase interacts indirectly with proteins like thymidylate synthase and dihydrofolate reductase through these pathways. These interactions aid in maintaining a steady supply of nucleotides important for DNA replication and repair.

Associated diseases and disorders

Impairments in dUTPase function can relate to cancer and immunodeficiency disorders. In some cancers altered dUTPase expression affects the sensitivity to chemotherapeutic agents particularly those targeting thymidylate synthesis. In certain immunodeficiencies dUTPase malfunction leads to increased uracil incorporation compromising DNA integrity. The enzyme connects with proteins such as thymidylate synthase in these diseases due to its role in managing nucleotide pools critical for cell proliferation.
