Metabolite Identification
Common Name5,6-Dihydro-5-fluorouracil
Description5,6-Dihydro-5-fluorouracil is a metabolite of fluorouracil. Fluorouracil (5-FU or f5U) (sold under the brand names Adrucil, Carac, Efudix, Efudex and Fluoroplex) is a drug that is a pyrimidine analog which is used in the treatment of cancer. It is a suicide inhibitor and works through irreversible inhibition of thymidylate synthase. It belongs to the family of drugs called antimetabolites. It is typically administered with leucovorin.

Enzymes

General function:
Involved in hydrolase activity
Specific function:
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.
