Electrochemical investigations of the heme protein dehaloperoxidase (DHP) were undertaken. The motivation for this work lies in the unusual bifunctional nature of DHP, a globin-type protein found in the marine worm Amphitrite ornata. DHP is a monomeric hemoglobin that not only binds and transports dioxygen but that features a high level of peroxidase activity for the enzymatic detoxification of...
