Summaries for DPYS Gene

Entrez Gene Summary for DPYS Gene

  • Dihydropyrimidinase catalyzes the conversion of 5,6-dihydrouracil to 3-ureidopropionate in pyrimidine metabolism. Dihydropyrimidinase is expressed at a high level in liver and kidney as a major 2.5-kb transcript and a minor 3.8-kb transcript. Defects in the DPYS gene are linked to dihydropyrimidinuria. [provided by RefSeq, Jul 2008]

GeneCards Summary for DPYS Gene

DPYS (Dihydropyrimidinase) is a Protein Coding gene. Diseases associated with DPYS include dihydropyrimidinuria and beta-ureidopropionase deficiency. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include phosphoprotein binding and dihydropyrimidinase activity. An important paralog of this gene is CRMP1.

UniProtKB/Swiss-Prot for DPYS Gene

  • Catalyzes the second step of the reductive pyrimidine degradation, the reversible hydrolytic ring opening of dihydropyrimidines. Can catalyze the ring opening of 5,6-dihydrouracil to N-carbamyl-alanine and of 5,6-dihydrothymine to N-carbamyl-amino isobutyrate
