Protein
Oxygen-independent coproporphyrinogen III oxidase
Organism
Escherichia coli (strain K12)
Function
Involved in the heme biosynthesis. Catalyzes the anaerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen III to yield the vinyl groups in protoporphyrinogen IX. It can use NAD or NADP, but NAD is preferred.
Similarity
Belongs to the anaerobic coproporphyrinogen-III oxidase family.
