THE CRYSTAL STRUCTURE OF DPS, A FERRITIN HOMOLOG THAT BINDS AND PROTECTS DNA
Overview
The crystal structure of Dps, a DNA-binding protein from starved E. coli, that protects DNA from oxidative damage, has been solved at 1.6 A, resolution. The Dps monomer has essentially the same fold as ferritin, which forms a 24-mer with 432 symmetry, a hollow core and pores at the, three-fold axes. Dps forms a dodecamer with 23 (tetrahedral) point group, symmetry which also has a hollow core and pores at the three-folds. The, structure suggests a novel DNA-binding motif and a mechanism for DNA, protection based on the sequestration of Fe ions.
