Abstract
A method producing a non-heme haloperoxidase which is substantially resistant to inactivation, at room temperature, in up to 0.3M H.sub.2 O.sub.2 for up to 25 hours, and up to 0.5mM HOCl for up to two minutes. One such haloperoxidase, isolated from Curvularia inaequalis, contains about 2 gram atoms of zinc per molecule. A halogenation reaction employing the enzyme can be performed at H.sub.2 O.sub.2 and hypohalous acid concentrations which produce rapid inactivation of heme-containing haloperoxidases.
