Chains	Enzyme Name	Description	Catalytic Residues
A	dUTP diphosphatase M-CSA #844	dUTP diphosphatase(dUTPase) hydrolyses dUTP to dUMP and pyrophosphate, simultaneously reducing dUTP levels and providing the dUMP for dTTP biosynthesis. This reaction is critical for the fidelity of DNA replication and repair as dUTPase decreases the intracellular concentration of dUPT so that uracil cannot be incorporated into DNA.
