== Function ==
[https://www.uniprot.org/uniprot/PRXC_LEPFU PRXC_LEPFU] Catalyzes peroxidative halogenations involved in the biosynthesis of clardariomycin (2,2-dichloro-1,3-cyclo-pentenedione). The enzyme also has potent catalase activity and in the absence of halide ion, acts as a peroxidase similar to plant peroxidases.

== Publication Abstract from PubMed ==
We have determined the crystal structure of the chloroperoxidase (CPO) hydroperoxo reaction intermediate (CPO compound 0) at 1.75-A resolution. The intermediate was generated through controlled photoreduction of the CPO oxygen complex during x-ray data collection, which was monitored by recording of the crystal absorption spectra. Initially, the peroxo-anion species was formed and then protonated to yield compound 0. Quantum chemical calculations indicate that the peroxo-anion species is not stable and collapses instantaneously to compound 0. Compound 0 is present in the ferric low-spin doublet ground state and is characterized by a long O O bond length of 1.5 A and a Fe O bond distance of 1.8 A, which is also observed in the crystal structure.
