It catalyses the decarboxylation of uroporphyrinogen III to coproporphyrinogen III by the conversion of four acetic acid groups to four methyl groups. Chemical name: Uroporphyrinogen-III carboxy-lyase Registry number: EC 4.1.1.37 (12 Dec 1998) |

| uroporphyrinogen | See: porphyrinogens. Uroporphyrinogen decarboxylase, an enzyme that participates in haem biosynthesis; it catalyses the decarboxylation of uroporphyrinogen III to produce coproporphyrinogen III; it also acts on uroporphyrinogen I; a deficiency of this enzyme will result in either porphyria cutanea tarda or hepatoerythropoietic porphyria. Uroporphyrinogen III cosynthase, an enzyme in haem biosynthesis that participates in the formation of uroporphyrinogen III; a deficiency of this protein results in congenital erythropoietic porphyria.

|---|---|
| uroporphyrinogen-III synthase | <enzyme> An enzyme that catalyses the cyclization of hydroxymethylbilane to yield uroporphyrinogen III and water. Chemical name: Hydroxymethylbilane hydro-lyase (cyclizing) Registry number: EC 4.2.1.75 (12 Dec 1998) |
| uroporphyrinogen I synthetase | <enzyme> An enzyme of haem biosynthesis that is defective in the inherited (autosomal dominant) disease, acute intermittent porphyria. UP I is isomerised to UP III by UP III synthetase, defective in the autosomal recessive disease, congenital erythropoietic porphyria. (18 Nov 1997) |
| adenosylmethionine decarboxylase | <enzyme> An enzyme that catalyses the decarboxylation of s-adenosyl-l-methionine to yield 5'-deoxy-(5'-),3-aminopropyl-(1), methylsulfonium salt.

Synonym: dopa decarboxylase, hydroxytryptophan decarboxylase, tryptophan decarboxylase. (05 Mar 2000) |
| aspartate 1-decarboxylase | <enzyme> A pyridoxal-phosphate protein that catalyses the alpha-decarboxylation of l-glutamic acid to form gamma-aminobutyric acid and carbon dioxide. The enzyme is found in bacteria and in invertebrate and vertebrate nervous systems. It is the rate-limiting enzyme in determining gaba levels in normal nervous tissues. The brain enzyme also acts on l-cysteate, l-cysteine sulfinate, and l-aspartate. Chemical name: L-Glutamate-1-carboxy-lyase Registry number: EC 4.1.1.15 (12 Dec 1998) |
| aspartate 4-decarboxylase | Aspartate beta-decarboxylase;a carboxy-lyase converting l-aspartate to l-alanine (releasing CO2); it decarboxylates aminomalonate and (in bacteria) removes SO2 from cysteinesulfinate. See: desulfinase. (05 Mar 2000) |
