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 PubMed SurE is a stationary-phase survival protein found in bacteria, eukaryotes and archaea that exhibits a divalent-metal-ion-dependent phosphatase activity and acts as a nucleotidase and polyphosphate phosphohydrolase. The structure of the SurE protein from the hyperthermophile Aquifex aeolicus has been solved at 1.5 A resolution using molecular replacement with one dimer in the asymmetric unit and refined to an R factor of 15.6%. The crystal packing reveals that two dimers assemble to form a tetramer, although gel-filtration chromatography showed the presence of only a dimer in solution. The phosphatase active-site pocket was occupied by sulfate ions from the crystallization medium.
