'''THE CRYSTAL STRUCTURE OF DPS, A FERRITIN HOMOLOG THAT BINDS AND PROTECTS DNA'''
===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.
The line below this paragraph, {{ABSTRACT_PUBMED_9546221}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 9546221 is the PubMed ID number.
