General description
Dihydrouracil (DiHU) is a minor base found in transfer ribonucleic acid (tRNA). It is similar to uracil with the only exception that the C5-C6 bond is saturated. It crystallized in the monoclinic system with space group P21/C. Its crystalline structure has been analyzed. Its generation from L-cysteine and uracil via photochemical addition has been described.
Application
Dihydrouracil has been used as a standard for ureido group in the colorimentric assay of transfer ribonucleic acid (tRNA).

The reductive pyrimidine catabolic pathway is absent in Escherichia coli. However, the bacterium contains an enzyme homologous to mammalian dihydropyrimidine dehydrogenase. Here, we show that E. coli dihydropyrimidine dehydrogenase is the first member of a novel NADH-dependent subclass of iron-sulfur
