EPSTEIN BARR VIRUS DUTPASE IN COMPLEX WITH A,B-IMINO DUTP
|
OverviewOverview
Deoxyuridine 5'-triphosphate pyrophosphatases (dUTPases) are ubiquitous, enzymes cleaving dUTP into dUMP and pyrophosphate. They occur as, monomeric, dimeric, or trimeric molecules. The trimeric and monomeric, enzymes both contain the same five characteristic sequence motifs but in a, different order, whereas the dimeric enzymes are not homologous. Monomeric, dUTPases only occur in herpesviruses, such as Epstein-Barr virus (EBV)., Here, we describe the crystal structures of EBV dUTPase in complex with, the product dUMP and a substrate analog alpha,beta-imino-dUTP. The, molecule consists of three domains forming one active site that has a, structure extremely similar to one of the three active sites of trimeric, dUTPases. The three domains functionally correspond to the subunits of the, ... [(full description)]
