uroporphyrinogen decarboxylase/cobalamine-independent methonine synthase family protein( domain architecture ID 1254)
uroporphyrinogen decarboxylase (URO-D)/cobalamine-independent methonine synthase (CIMS) family protein, similar to URO-D that decarboxylates the four acetate side chains of uroporphyrinogen III (uro-III) to create coproporphyrinogen III, an important branching point of the tetrapyrrole biosynthetic pathway

The URO-D_CIMS_like protein superfamily includes bacterial and eukaryotic uroporphyrinogen decarboxylases (URO-D), coenzyme M methyltransferases and other putative bacterial methyltransferases, as well as cobalamine (B12) independent methionine synthases. Despite their sequence similarities, members of this family have clearly different functions. Uroporphyrinogen decarboxylase (URO-D) decarboxylates the four acetate side chains of uroporphyrinogen III (uro-III) to create coproporphyrinogen III, an important branching point of the tetrapyrrole biosynthetic pathway. The methyltransferases represented here are important for ability of methanogenic organisms to use other compounds than carbon dioxide for reduction to methane, and methionine synthases transfer a methyl group from a folate cofactor to L-homocysteine in a reaction requiring zinc.

MtaA_CmuA_like family. MtaA/CmuA, also MtsA, or methyltransferase 2 (MT2) MT2-A and MT2-M isozymes, are methylcobamide:Coenzyme M methyltransferases, which play a role in metabolic pathways of methane formation from various substrates, such as methylated amines and methanol. Coenzyme M, 2-mercaptoethylsulfonate or CoM, is methylated during methanogenesis in a reaction catalyzed by three proteins. A methyltransferase methylates the corrinoid cofactor, which is bound to a second polypeptide, a corrinoid protein. The methylated corrinoid protein then serves as a substrate for MT2-A and related enzymes, which methylate CoM.

Uroporphyrinogen decarboxylase (URO-D) is a dimeric cytosolic enzyme that decarboxylates the four acetate side chains of uroporphyrinogen III (uro-III) to create coproporphyrinogen III, without requiring any prosthetic groups or cofactors. This reaction is located at the branching point of the tetrapyrrole biosynthetic pathway, leading to the biosynthesis of heme, chlorophyll or bacteriochlorophyll. URO-D deficiency is responsible for the human genetic diseases familial porphyria cutanea tarda (fPCT) and hepatoerythropoietic porphyria (HEP).

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.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

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.

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)
