CC -!- FUNCTION: During stationary phase, binds the chromosome non-
CC specifically, forming a highly ordered and stable dps-DNA co-crystal
CC within which chromosomal DNA is condensed and protected from diverse
CC damages. It protects DNA from oxidative damage by sequestering
CC intracellular Fe(2+) ion and storing it in the form of Fe(3+)
CC oxyhydroxide mineral, which can be released after reduction. One
CC hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl
CC radical production by the Fenton reaction. {ECO:0000255|HAMAP-
CC Rule:MF_01441}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 Fe(2+) + 2 H(+) + H2O2 = 2 Fe(3+) + 2 H2O;
CC Xref=Rhea:RHEA:48712, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16240, ChEBI:CHEBI:29033, ChEBI:CHEBI:29034;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01441};
CC -!- SUBUNIT: Homododecamer. The 12 subunits form a hollow sphere into which
CC the mineral iron core of up to 500 Fe(3+) can be deposited.
CC {ECO:0000255|HAMAP-Rule:MF_01441}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01441}.
CC -!- SIMILARITY: Belongs to the Dps family. {ECO:0000255|HAMAP-
CC Rule:MF_01441}.
