Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III, the branch point for the various sub-pathways leading to the wide diversity of porphyrins. Porphyrins act as cofactors for a multitude of enzymes that perform a variety of processes within the cell such as methionine synthesis (vitamin B12) or oxygen transport (heme).

Catalytic activityi

Hydroxymethylbilane = uroporphyrinogen III + H2O.1 Publication

Pathway: protoporphyrin-IX biosynthesis

This protein is involved in step 3 of the subpathway that synthesizes coproporphyrinogen-III from 5-aminolevulinate.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Delta-aminolevulinic acid dehydratase (ALAD)
  2. Porphobilinogen deaminase (HMBS)
  3. Uroporphyrinogen-III synthase (UROS)
  4. Uroporphyrinogen decarboxylase (UROD)
This subpathway is part of the pathway protoporphyrin-IX biosynthesis, which is itself part of Porphyrin-containing compound metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes coproporphyrinogen-III from 5-aminolevulinate, the pathway protoporphyrin-IX biosynthesis and in Porphyrin-containing compound metabolism.

Involvement in diseasei

Congenital erythropoietic porphyria (CEP)13 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionPorphyrias are inherited defects in the biosynthesis of heme, resulting in the accumulation and increased excretion of porphyrins or porphyrin precursors. They are classified as erythropoietic or hepatic, depending on whether the enzyme deficiency occurs in red blood cells or in the liver. The manifestations of CEP are heterogeneous, ranging from nonimmune hydrops fetalis due to severe hemolytic anemia in utero to milder, later onset forms, which have only skin lesions due to cutaneous photosensitivity in adult life. The deficiency in UROS activity results in the non-enzymatic conversion of hydroxymethylbilane (HMB) into the uroporphyrinogen-I isomer.

Severe congenital erythropoietic porphyria is associated with non-immune hydrops fetalis, a generalized edema of the fetus with fluid accumulation in the body cavities due to non-immune causes. Non-immune hydrops fetalis is not a diagnosis in itself but a symptom, a feature of many genetic disorders, and the end-stage of a wide variety of disorders.

Caution

Variant Ala-62 was originally reported to result in no detectable enzyme activity (PubMed:1737856), as measured in recombinant crude lysate extracts. Further experiments with the purified enzyme have shown that this variant does not affect activity (PubMed:11689424).2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
