== 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 ==
 +
The X-ray crystallographic analysis of redox-active systems may be complicated by photoreduction. Although radiolytic reduction by the probing X-ray beam may be exploited to generate otherwise short-lived reaction intermediates of metalloproteins, it is generally an undesired feature. Here, the X-ray-induced reduction of the three heme proteins myoglobin, cytochrome P450cam and chloroperoxidase has been followed by on-line UV-Vis absorption spectroscopy. All three systems showed a very rapid reduction of the heme iron. In chloroperoxidase the change of the ionization state from ferric to ferrous heme is associated with a movement of the heme-coordinating water molecule. The influence of the energy of the incident X-ray photons and of the presence of scavengers on the apparent reduction rate of ferric myoglobin crystals was analyzed.
