Coprogen oxidase (i.e. coproporphyrin III oxidase or coproporphyrinogenase) catalyses the oxidative decarboxylation of coproporphyrinogen III to proto-porhyrinogen IX in the haem and chlorophyll biosynthetic pathways [1, 2]. The protein is a homodimer containing two internally bound iron atoms per molecule of native protein [3]. The enzyme is active in the presence of molecular oxygen that acts as an electron acceptor. The enzyme is widely distributed having been found in a variety of eukaryotic and prokaryotic sources.	Domain
