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]

oxygen-independent coproporphyrinogen III oxidase; This model represents HemN, the oxygen-independent coproporphyrinogen III oxidase that replaces HemF function under anaerobic conditions. 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.

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.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
click on the bars or triangles to view your query sequence embedded in a multiple sequence alignment of the proteins used to develop the corresponding domain model.
The table lists conserved domains identified on the query sequence. Click on the plus sign (+) on the left to display full descriptions, alignments, and scores.
Click on the domain model's accession number to view the multiple sequence alignment of the proteins used to develop the corresponding domain model.
To view your query sequence embedded in that multiple sequence alignment, click on the colored bars in the Graphical Summary portion of the search results page,
or click on the triangles, if present, that represent functional sites (conserved features)
mapped to the query sequence.
Concise Display shows only the best scoring domain model, in each hit category listed below except non-specific hits, for each region on the query sequence.
(labeled illustration) Standard Display shows only the best scoring domain model from each source, in each hit category listed below for each region on the query sequence.
(labeled illustration) Full Display shows all domain models, in each hit category below, that meet or exceed the RPS-BLAST threshold for statistical significance.
(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
advanced search options)
