Dihydroorotate dehydrogenase (DHODH) is an enzyme that in humans is encoded by the DHODH gene on chromosome 16. The protein encoded by this gene catalyzes the fourth enzymatic step, the ubiquinone-mediated oxidation of dihydroorotate to orotate, in de novo pyrimidine biosynthesis. This protein is a mitochondrial protein located on the outer surface of the inner mitochondrial membrane (IMM). Inhibitors of this enzyme are used to treat autoimmune diseases such as rheumatoid arthritis.

  • La dihydroorotate déshydrogénase est une oxydoréductase qui catalyse la réaction : (S)-dihydroorotate + fumarate orotate + succinate. Cette enzyme intervient dans la biosynthèse de novo des pyrimidines. Chez l'homme, elle utilise le FMN comme cofacteur. Chez les bactéries, elle est encodée par le gène pyrD et est localisée sur la face interne de la membrane plasmique ; chez certaines levures, comme Saccharomyces cerevisiae, elle est située dans le cytosol, tandis que chez d'autres eucaryotes elle est présente dans les mitochondries. (fr)
  • La diidroorotato ossidasi è un enzima appartenente alla classe delle ossidoreduttasi, che catalizza la seguente reazione: (S)-diidroorotato + O2 ⇄ orotato + H2O2 L'enzima è una flavoproteina (FAD, FMN). Il cianuro ferrico può agire come accettore. (it)
  • Diidroorotato desidrogenase (abreviada na literatura em inglês DHODH, de dihydroorotate dehydrogenase) é uma enzima que em humanos é codificado pelo gene DHODH no cromossomo 16. A proteína codificada por este gene catalisa a quarta etapa enzimática, a oxidação mediada por ubiquinona de diidroorotato a orotato, na biossíntese de pirimidina. Esta proteína é uma proteína mitocondrial localizado na superfície externa da membrana mitocondrial interna (MMI). Inibidores desta enzima são usados para tratar doenças autoimune tais como artrite reumatoide. (pt)
  • 二氢乳清酸脱氢酶(DHODH)是由人类16号染色体上的DHODH基因编码的酶。由该基因编码的酶在嘧啶的从头合成(de novo synthesis)中催化第四步酶促步骤,即泛醌介导的二氢乳清酸氧化为乳清酸。该蛋白是位于线粒体内膜(IMM)外表面的线粒体蛋白。这种酶的抑制剂用于治疗自體免疫性疾病,如类风湿性关节炎。 (zh)
