| Common Name | Uroporphyrinogen III |
|---|
| Description | Uroporphyrinogen III, also known as uro'gen III, belongs to the class of organic compounds known as porphyrins. Porphyrins are compounds containing a fundamental skeleton of four pyrrole nuclei united through the alpha-positions by four methine groups to form a macrocyclic structure. Uroporphyrinogen III is a weakly acidic compound (based on its pKa). Uroporphyrinogen III exists in all living species, ranging from bacteria to humans. In humans, uroporphyrinogen III is involved in the metabolic disorder called the acute intermittent porphyria pathway. Outside of the human body, Uroporphyrinogen III has been detected, but not quantified in, several different foods, such as rices, gram beans, garden onions, grapes, and natal plums. This could make uroporphyrinogen III a potential biomarker for the consumption of these foods. The molecular structure of uroporphyrinogen III can be described as a hexahydroporphine core, where each pyrrole ring has the hydrogen atoms on its two outermost carbons replaced by an acetic acid group (−CH2−COOH, "A") and a propionic acid group (−CH2−CH2−COOH, "P"). If uroporphyrinogen-III synthase is not present or inactive, the hydroxymethylbilane will spontaneously cyclise into the structural isomer uroporphyrinogen I, which differs from the III isomer in that the acetic acid ("A") and propionic acid ("P") groups are arranged in a rotationally symmetric order, AP-AP-AP-AP. In the biosynthesis of sirohemes, uroporphyrinogen III is converted by two methyl transferases to dihydrosirohydrochlorin, which is subsequently oxidized sirohydrochlorin, a precursor to the siroheme prosthetic group. It is a colorless compound, like other porphyrinogens. The conversion entails a reversal of the last pyrrole unit (thus swapping the acetic and propionic acid groups) and a condensation reaction that closes the macrocycle by eliminating the final hydroxyl −OH with a hydrogen atom of the first ring. Uroporphyrinogen III is a tetrapyrrole, the first macrocyclic intermediate in the biosynthesis of heme, chlorophyll, vitamin B12, and siroheme. The groups are attached in an asymmetric way: Going around the macrocycle, the order is AP-AP-AP-PA.In the general porphyrin biosynthesis pathway, uroporphyrinogen III is derived from the linear tetrapyrrole preuroporphyrinogen (a substituted hydroxymethylbilane) by the action of the enzyme uroporphyrinogen-III cosynthase. Uroporphyrinogen III is found in Apis cerana, Arabidopsis thaliana and Escherichia coli K12. Uroporphyrinogen III was first documented in 2000 (PMID: 11112350). In the biosynthesis of hemes and chlorophylls, uroporphyrinogen III is converted into coproporphyrinogen III by the enzyme uroporphyrinogen III decarboxylase (PMID: 11524417). |
