Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMeddUTPase is an essential enzyme involved with nucleotide metabolism and replication. We report here the X-ray structure of Trypanosoma cruzi dUTPase in its native conformation and as a complex with dUDP. These reveal a novel protein fold that displays no structural similarities to previously described dUTPases. The molecular unit is a dimer with two active sites. Nucleotide binding promotes extensive structural rearrangements, secondary structure remodeling, and rigid body displacements of 20 A or more, which effectively bury the substrate within the enzyme core for the purpose of hydrolysis. The molecular complex is a trapped enzyme-substrate arrangement which clearly demonstrates structure-induced specificity and catalytic potential. This enzyme is a novel dUTPase and therefore a potential drug target in the treatment of Chagas' disease. The crystal structure of Trypanosoma cruzi dUTPase reveals a novel dUTP/dUDP binding fold.,Harkiolaki M, Dodson EJ, Bernier-Villamor V, Turkenburg JP, Gonzalez-Pacanowska D, Wilson KS Structure. 2004 Jan;12(1):41-53.
