| decarboxylase | Any enzyme (EC subclass 4.1.1) that removes a molecule of carbon dioxide from a carboxylic group (e.g., from an alpha-amino acid, converting it into an amine). (05 Mar 2000) |
|---|---|
| indolepyruvate decarboxylase | <enzyme> From enterobacter cloacae; catalyses the conversion of indole-3-pyruvic acid to indole-3-acetaldehyde Registry number: EC 4.1.1- Synonym: ipdcase (26 Jun 1999) |
| OMP decarboxylase | <enzyme> An enzyme that catalyses the conversion of OMP to UMP and CO2; a defect or inhibition of this enzyme will result in orotic aciduria and orotidinuria; this enzyme is a part of pyrimidine biosynthesis. Compare: uridylic acid synthase. Synonym: OMP decarboxylase. (05 Mar 2000) |
| ornithine decarboxylase | <enzyme> The enzyme that converts ornithine to putrescine (dibasic amine) by decarboxylation. Rate limiting in the synthesis of the polyamines spermidime and spermine that regulate DNA synthesis. (18 Nov 1997) |
| orotidine-5'-phosphate decarboxylase | <enzyme> Orotidine-5'-phosphate carboxy-lyase. Catalyses the decarboxylation of orotidylic acid to yield uridylic acid in the final step of the pyrimidine nucleotide biosynthesis pathway.
