DPS FROM DEINOCOCCUS RADIODURANS
Overview
The crystal structure of a DNA-binding protein from starved cells (Dps), (DR2263) from Deinococcus radiodurans was determined in two states: a, native form, to 1.1-A resolution, and one soaked in an iron solution, to, 1.6-A resolution. In comparison with other Dps proteins, DR2263 has an, extended N-terminal extension, in both structures presented here, a novel, metal binding site was identified in this N-terminal extension and was, assigned to bound zinc. The zinc is tetrahedrally coordinated and the, ligands, that belong to the N-terminal extension, are two histidines, one, glutamate and one aspartate residue, which are unique to this protein, within the Dps family. In the iron-soaked crystal structure, a total of, three iron sites per monomer were found: one site corresponds to the, ... [(full description)]
