UniProtKB description:  Heme-containing oxidoreductase which catalyzes the conversion of thiocyanate (SCN(-)) into antimicrobial agent hypothiocyanous acid (OSCN(-)) in the presence of hydrogen peroxide (H2O2) (By similarity). Also involved in the conversion of iodide (I(-)) into hypoiodite (IO(-)) in the presence of H2O2 (By similarity). Responsible for the inactivation of a wide range of micro-organisms and hence, important component of defense mechanism (PubMed:10894086). Shows antibacterial properties against several Gram-positive bacteria including some Staphylococcus species and Gram-negative bacteria including E.coli, P.aeruginosa and some Salmonella species (PubMed:10894086). Inhibits the growth of several fungi including A.niger, Trichoderma species, C.cassicola, P.meadii and C.salmonicolor (PubMed:10894086). Does not have anti-fungal activity towards C.albicans and Pythium species (PubMed:10894086). May protect the udder from infection and may promote growth in newborns (PubMed:10894086). May be implicated in airway host defense against infection (By similarity). May contribute to maintaining an appropriate H2O2 cellular level, therefore protecting cells from H2O2-caused injuries and inflammation (By similarity).
