Dihydrouracil is an intermediate in the catabolism of uracil. [1] It is the base present in the nucleoside dihydrouridine.

5,6-dihydrouracil is a pyrimidine obtained by formal addition of hydrogen across the 5,6-position of uracil. It has a role as a metabolite, a human metabolite, an Escherichia coli metabolite and a mouse metabolite.

Dihydrouracil is a compound formed in the pyrimidine metabolic pathway through the conversion of uracil, and it plays a crucial role in various biological processes. You might find these chapters and articles relevant to this topic.

Dihydrouracil, an ionizing radiation-induced DNA damage product, is readily bypassed by phage (T7 and SP6) and E. coli RNA polymerases, although it causes brief pausing before efficient readthrough [13,15]. Like uracil, dihydrouracil causes primarily insertions of A resulting in C to T base substitution transition mutation in the transcripts.

Dihydrouracil (DiHU) is a minor base found in transfer ribonucleic acid (tRNA). It is similar to uracil with the only exception that the C 5 -C 6 bond is saturated. It crystallized in the monoclinic system with space group P 2 1 / C .
