PubMed Abstract:
Chloroperoxidase (CPO) is a versatile heme-containing enzyme that exhibits peroxidase, catalase and cytochrome P450-like activities in addition to catalyzing halogenation reactions. The structure determination of CPO was undertaken to help elucidate those structural features that enable the enzyme to exhibit these multiple activities.
