A new chloroperoxidase could be detected in Pseudomonas pyrrocinia ATCC 15 958, a bacterium that produces the antifungal antibiotic pyrrolnitrin. This enzyme was separated from a ferriprotoporphyrin IX containing bromoperoxidase which was also produced by this bacterium. The enzyme is capable of catalyzing the chorination of indole to 7‐chloroindole. This procaryotic chloroperoxidase requires the presence of H 2 O 2 and can also brominate monochlorodimedone, but cannot catalyze its chlorination. This enzyme is the first chloroperoxidase described from procaryotic sources.
