== Function ==
[https://www.uniprot.org/uniprot/DCDB_METJA DCDB_METJA] Bifunctional enzyme that catalyzes both the deamination of dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the toxic dUTP intermediate. It also acts as a dUTP diphosphatase with a lower affinity for dUTP than for dCTP.<ref>PMID:12538648</ref> <ref>PMID:12670946</ref>
