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
Proteins similar to dps have been found in other bacteria:
Bacillus subtilis protein mrgA.
Antigen TpF1/TyF1 from Treponema pallidum and pertenue.
Haemophilus ducreyi fine tangled pili major subunit (gene ftpA).
Helicobacter pylori neutrophil-activating protein A (gene napA).
