Protein Domain : DNA-binding protein Dps, conserved site IPR023188

Type	Conserved_site
Description	Escherichia coli protein Dps [ ] is a DNA-binding protein, synthesized during prolonged starvation, that seems to protect DNA from oxidative damage. Dps binds DNA without any apparent sequence specificity. It is a protein of about 19 Kd that associates into a complex of 12 subunits forming two stacked hexameric rings.Proteins similar to Dps have been found in other bacteria:Bacillus subtilis protein MrgA.Antigen TpF1/TyF1 from Treponema pallidum.Haemophilus ducreyi fine tangled pili major subunit (gene ftpA).Helicobacter pylori neutrophil-activating protein A (gene napA).Listeria innocua non-heme iron-containing ferritin.Synechococcus elongatus (strain PCC 7942) (Anacystis nidulans R2) nutrient-stress induced DNA binding protein (gene dpsA).A low-temperature induced protein from Anabaena variabilis.Haemophilus influenzae hypothetical protein HI1349.Synechocystis sp. (strain PCC 6803) hypothetical protein Slr1894.A hypothetical protein encoded in the 5' region of a gene coding for a bromoperoxidase, in plasmid pOP2621 of Streptomyces aureofaciens.All these proteins share a conserved region of about 50 residues in their central region. This entry corresponds to two conserved sites derived from both extremities of that region.
