In [[enzymology]], a '''dUTP diphosphatase''' ({{EC number|3.6.1.23}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]


:dUTP + H<sub>2</sub>O <math>\rightleftharpoons</math> dUMP + diphosphate
Here is my website :: [http://www.kalamazoooptometry.com/mediac/p/r/jimmychoo/ ジミーチュウ 財布 新作]
 
Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[dUTP]] and [[water|H<sub>2</sub>O]], whereas its two [[product (chemistry)|products]] are [[dUMP]] and [[diphosphate]].
 
This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on acid anhydrides in phosphorus-containing anhydrides.  The systematic name of this enzyme class is '''dUTP nucleotidohydrolase'''. Other names in common use include '''deoxyuridine-triphosphatase''', '''dUTPase''', '''dUTP pyrophosphatase''', '''desoxyuridine 5'-triphosphate nucleotidohydrolase''', and '''desoxyuridine 5'-triphosphatase'''.  This enzyme participates in [[pyrimidine metabolism]].
 
This enzyme has a dual function: on one hand, it removes dUTP from the [[nucleotide|deoxynucleotide]] pool, which reduces the probability of this base being incorporated into [[DNA]] by [[DNA polymerase]]s, while on the other hand, it produces the dTTP precursor dUMP. Lack or inhibition of dUTPase action leads to harmful perturbations in the nucleotide pool resulting in increased uracil content of DNA that activates a hyperactive futile cycle of DNA repair.<ref>{{cite journal |author=Vertessy BG, Toth J |title=Keeping uracil out of DNA |journal=Accounts of Chemical Research |volume=42 |issue=1 |pages=97–106 |year=2009 |pmid=18837522|doi=10.1021/ar800114w}}</ref><ref>{{cite journal |author=Vassylyev DG, Morikawa K |title=Precluding uracil from DNA |journal=Structure |volume=4 |issue=12 |pages=1381–5 |year=1996 |pmid=8994964 |doi=10.1016/S0969-2126(96)00145-1}}</ref>
 
==Structural studies==
 
As of late 2007, 48 [[tertiary structure|structures]] have been solved for this class of enzymes, with [[Protein Data Bank|PDB]] accession codes {{PDB link|1DUC}}, {{PDB link|1DUD}}, {{PDB link|1DUN}}, {{PDB link|1DUP}}, {{PDB link|1DUT}}, {{PDB link|1EU5}}, {{PDB link|1EUW}}, {{PDB link|1F7D}}, {{PDB link|1F7K}}, {{PDB link|1F7N}}, {{PDB link|1F7O}}, {{PDB link|1F7P}}, {{PDB link|1F7Q}}, {{PDB link|1F7R}}, {{PDB link|1MQ7}}, {{PDB link|1OGH}}, {{PDB link|1OGK}}, {{PDB link|1OGL}}, {{PDB link|1PKH}}, {{PDB link|1PKJ}}, {{PDB link|1PKK}}, {{PDB link|1RN8}}, {{PDB link|1RNJ}}, {{PDB link|1SEH}}, {{PDB link|1SIX}}, {{PDB link|1SJN}}, {{PDB link|1SLH}}, {{PDB link|1SM8}}, {{PDB link|1SMC}}, {{PDB link|1SNF}}, {{PDB link|1SYL}}, {{PDB link|1VYQ}}, {{PDB link|1W2Y}}, {{PDB link|2BSY}}, {{PDB link|2BT1}}, {{PDB link|2CJE}}, {{PDB link|2D4L}}, {{PDB link|2D4M}}, {{PDB link|2D4N}}, {{PDB link|2HQU}}, {{PDB link|2HR6}}, {{PDB link|2HRM}}, {{PDB link|2OKB}}, {{PDB link|2OKD}}, {{PDB link|2OKE}}, {{PDB link|2OL0}}, {{PDB link|2OL1}}, and {{PDB link|2PY4}}.
 
There are at least two structurally distinct families of dUTPases. The [[crystal structure]] of [[Homo sapiens|human]] dUTPase reveals that each subunit of the dUTPase [[Trimer (biochemistry)|trimer]] [[protein folding|fold]]s into an eight-stranded jelly-roll beta barrel, with the C-terminal [[beta sheet|beta strands]] interchanged among the [[protein subunit|subunits]]. The [[secondary structure|structure]] is similar to that of the ''[[Escherichia coli]]'' enzyme, despite low [[sequence homology]] between the two [[enzymes]].<ref name="pmid8805593">{{cite journal | author = Mol CD, Harris JM, McIntosh EM, Tainer JA | title = Human dUTP pyrophosphatase: uracil recognition by a beta hairpin and active sites formed by three separate subunits | journal = Structure | volume = 4 | issue = 9 | pages = 1077–92 |date=September 1996 | pmid = 8805593 | doi = 10.1016/S0969-2126(96)00114-1| url = }}</ref>
 
The second family has a novel all-alpha [[protein folding|fold]], members of this family are unrelated to the all-beta [[tertiary structure|fold]] found in dUTPases of the majority of [[organism]]s.<ref name="pmid15364583">{{Cite pmid|15364583}}</ref>
