== Publication Abstract from PubMed ==
Selenophosphate synthetase (SPS) catalyzes the activation of selenide with ATP to synthesize selenophosphate, the reactive selenium donor for biosyntheses of both the 21st amino acid selenocysteine and 2-selenouridine nucleotides in tRNA anticodons. The crystal structure of an N-terminally (25 residues) truncated fragment of SPS (SPS-DeltaN) from Aquifex aeolicus has been determined at 2.0 A resolution. The structure revealed SPS to be a two-domain alpha/beta protein, with domain folds that are homologous to those of PurM-superfamily proteins. In the crystal, six monomers of SPS-DeltaN form a hexamer of 204 kDa, whereas the molecular weight estimated by ultracentrifugation was approximately 63 kDa, which is comparable to the calculated weight of the dimer (68 kDa).
