CC -!- FUNCTION: Catalyzes the heme-dependent decomposition of chlorite to
CC O(2) and chloride with high efficiency and specificity. Used to
CC detoxify chlorite, a by-product of the reduction of perchlorate, a
CC primarily anthropogenic pollutant, in perchlorate-respiring bacteria.
CC {ECO:0000269|PubMed:11472023, ECO:0000269|PubMed:22492460}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=chloride + O2 = chlorite; Xref=Rhea:RHEA:21404,
CC ChEBI:CHEBI:15379, ChEBI:CHEBI:17441, ChEBI:CHEBI:17996;
CC EC=1.13.11.49; Evidence={ECO:0000269|PubMed:11472023};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000269|PubMed:11472023, ECO:0000269|PubMed:12359335};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per monomer.
CC {ECO:0000269|PubMed:11472023, ECO:0000269|PubMed:12359335};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.26 mM for chlorite {ECO:0000269|PubMed:11472023};
CC Vmax=4.3 mmol/min/mg enzyme {ECO:0000269|PubMed:11472023};
CC -!- SUBUNIT: Homopentamer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000269|PubMed:11472023}.
CC -!- INDUCTION: Expressed under aerobic conditions. Significantly increased
CC upon shift to anaerobic conditions. {ECO:0000269|PubMed:22492460}.
CC -!- SIMILARITY: Belongs to the chlorite dismutase family. {ECO:0000305}.
