putative oxygen-independent coproporphyrinogen III oxidase; Experimentally determined examples of oxygen-independent coproporphyrinogen III oxidase, an enzyme that replaces HemF function under anaerobic conditions, belong to a family of proteins described by the model hemN. This model, hemN_rel, models a closely related protein, shorter at the amino end and lacking the region containing the motif PYRT[SC]YP found in members of the hemN family. Several species, including E. coli, Helicobacter pylori, Aquifex aeolicus, and Chlamydia trachomatis, have members of both this family and the E. coli hemN family. The member of this family from Bacillus subtilis was shown to complement an hemF/hemN double mutant of Salmonella typimurium and to prevent accumulation of coproporphyrinogen III under anaerobic conditions, but the exact role of this protein is still uncertain. It is found in a number of species that do not synthesize heme de novo. [Biosynthesis of cofactors, prosthetic groups, and carriers, Heme, porphyrin, and cobalamin]

Radical SAM superfamily. Enzymes of this family generate radicals by combining a 4Fe-4S cluster and S-adenosylmethionine (SAM) in close proximity. They are characterized by a conserved CxxxCxxC motif, which coordinates the conserved iron-sulfur cluster. Mechanistically, they share the transfer of a single electron from the iron-sulfur cluster to SAM, which leads to its reductive cleavage to methionine and a 5'-deoxyadenosyl radical, which, in turn, abstracts a hydrogen from the appropriately positioned carbon atom. Depending on the enzyme, SAM is consumed during this process or it is restored and reused. Radical SAM enzymes catalyze steps in metabolism, DNA repair, the biosynthesis of vitamins and coenzymes, and the biosynthesis of many antibiotics. Examples are biotin synthase (BioB), lipoyl synthase (LipA), pyruvate formate-lyase (PFL), coproporphyrinogen oxidase (HemN), lysine 2,3-aminomutase (LAM), anaerobic ribonucleotide reductase (ARR), and MoaA, an enzyme of the biosynthesis of molybdopterin.

putative heme utilization radical SAM enzyme HutW; HutW is a radical SAM enzyme closely related to HemN, the heme biosynthetic oxygen-independent coproporphyrinogen oxidase. It belongs to operons associated with heme uptake and utilization in Vibrio cholerae and related species, but neither it not HutX has been shown to be needed, as is HutZ, for heme utilization. HutW failed to complement a Salmonella enterica hemN mutant (), suggesting a related but distinct activity. Some members of this family are fused to hutX.

Several species, including E. coli, Helicobacter pylori, and Aquifex aeolicus, have both a member of this family and a member of another, closely related family for which there is no evidence of coproporphyrinogen III oxidase activity. Members of this family have a perfectly conserved motif PYRT[SC]YP in a region N-terminal to the region of homology with the related uncharacterized protein.

HemN C-terminal domain; Members of this family are all oxygen-independent coproporphyrinogen-III oxidases (HemN). This enzyme catalyzes the oxygen-independent conversion of coproporphyrinogen-III to protoporphyrinogen-IX, one of the last steps in haem biosynthesis. The function of this domain is unclear, but comparison to other proteins containing a radical SAM domain (pfam04055) suggest it may be a substrate binding domain.
