    The essential enzyme dUTP pyrophosphatase (dUTPase) is exquisitely specific for dUTP and is critical for the fidelity of DNA replication and repair. dUTPase hydrolyzes dUTP to dUMP and pyrophosphate, simultaneously reducing dUTP levels and providing the dUMP for dTTP biosynthesis. A high cellular dTTP: dUTP ratio is essential to avoid uracil incorporation into DNA, which would lead to strand breaks and cell death. We report the first detailed atomic-resolution structure of a eukaryotic dUTPase, human dUTPase, and complexes with the uracil-containing deoxyribonucleotides, dUMP, dUDP and dUTP.
