dUTP + H2O | Homo sapiens | dUTP is constantly produced in the pyrimidine biosynthesis network. To prevent uracil incorporation into DNA, representatives of the dUTP nucleotidohydrolase enzyme family eliminate excess dUTP as one moethod to avoid uracil nucleotides incorporation into DNA, besides exchanging dUTP for dTTP as a second method, overview | dUMP + diphosphate | dUMP is required for de novo biosynthesis of thymine | ? |

dUTP + H2O | catalysis proceeds by way of an SN2 mechanism, a water molecule initiates in-line nucleophilic attack, conformational changes during the reaction take place in the C-terminus. The dUTPase binding pocket is highly specific for uracil, structural basis, overview. Phosphate chain coordination involves Mg2+ and is analogous to that of DNA polymerases.
