General annotation (Comments)

Function	Anaerobic transformation of coproporphyrinogen-III into protoporphyrinogen-IX By similarity.
Catalytic activity	Coproporphyrinogen-III + 2 S-adenosyl-L-methionine = protoporphyrinogen-IX + 2 CO(2) + 2 L-methionine + 2 5'-deoxyadenosine.
Cofactor	Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.
Pathway	Porphyrin metabolism; protoporphyrin-IX biosynthesis; protoporphyrinogen-IX from coproporphyrinogen III (AdoMet route): step 1/1.
Subunit structure	Monomer.
Subcellular location	Cytoplasm.
Induction	Induced, in anaerobic conditions, by resDE, fnr and arfM.
Sequence similarities	Belongs to the anaerobic coproporphyrinogen III oxidase family.
