 -!- FUNCTION: Catalyzes the heme-dependent decomposition of chlorite
     to O(2) and chloride with high efficiency and specificity. Used to
     detoxify chlorite, a by-product of the reduction of perchlorate, a
     primarily anthropogenic pollutant, in perchlorate-respiring
     bacteria. {ECO:0000269|PubMed:11472023,
     ECO:0000269|PubMed:22492460}.
 -!- CATALYTIC ACTIVITY: Chloride + O(2) = chlorite.
     {ECO:0000269|PubMed:11472023}.
 -!- COFACTOR:
     Name=heme b; Xref=ChEBI:CHEBI:60344;
       Evidence={ECO:0000269|PubMed:11472023,
       ECO:0000269|PubMed:12359335};
     Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per
     monomer. {ECO:0000269|PubMed:11472023,
     ECO:0000269|PubMed:12359335};
 -!- BIOPHYSICOCHEMICAL PROPERTIES:
     Kinetic parameters:
       KM=0.26 mM for chlorite {ECO:0000269|PubMed:11472023};
       Vmax=4.3 mmol/min/mg enzyme {ECO:0000269|PubMed:11472023};
 -!- SUBUNIT: Homopentamer. {ECO:0000250}.
 -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000269|PubMed:11472023}.
 -!- INDUCTION: Expressed under aerobic conditions. Significantly
     increased upon shift to anaerobic conditions.
     {ECO:0000269|PubMed:22492460}.
 -!- SIMILARITY: Belongs to the chlorite dismutase family.
     {ECO:0000305}.
