Dihydrouridine

Dihydrouridine (abbreviated as D, DHU, or UH2) is a pyrimidine nucleoside which is the result of adding two hydrogen atoms to a uridine, making it a fully saturated pyrimidine ring with no remaining double bonds. D is found in tRNA and rRNA molecules as a nucleoside; the corresponding nucleobase is 5,6-dihydrouracil Dihydrouridine (abbreviated as D, DHU, or UH 2) is a pyrimidine which is the result of adding two hydrogen atoms to a uridine, making it a fully saturated pyrimidine ring with no remaining double bonds.D is found in tRNA and rRNA molecules as a nucleoside; the corresponding nucleobase is 5,6-dihydrouracil..

Catalyzes the synthesis of dihydrouridine, a modified base found in the D-loop of most tRNAs. Specifically modifies U20a and U20b in cytoplasmic tRNAs Dihydrouridine (D) is a highly conserved modified base found in tRNAs from all domains of life. Dihydrouridine synthase (Dus) catalyzes the D formation of tRNA through reduction of uracil base with flavin mononucleotide (FMN) as a cofactor. Here, we report the crystal structures of Thermus thermophilus Dus ( Tth Dus), which is responsible for D formation at positions 20 and 20a, in complex.

Introduction. Dihydrouridine is the single most common form of post-transcriptional modification in tRNA from bacteria and eukaryotes (1, 2) out of >70 modifications known to occur in these two phylogenetic domains ().Some of the clearest and most compelling evidence for functional roles of tRNA modification has been from studies which have demonstrated enhanced structural stabilization Dihydrouridine synthase catalyzes reduction of the 5,6-double bond of a uridine residue on the displacement loop of tRNA. The resultant modified base, 5,6-dihydrouridine, appears to increase the conformational flexibility and dynamic motion of tRNA (Kato et al., 2005). Cloning and Expressio Dihydrouridine (abbreviated as D, DHU, or UH2) is a pyrimidine nucleoside which is the result of adding two hydrogen atoms to a uridine, making it a fully saturated pyrimidine ring with no remaining double bonds. D is found in tRNA and rRNA molecules as a nucleoside; the corresponding nucleobase i Dihydrouridine (DHU) reduction and benzohydrazide substitution. A clear understanding of the chemistry of DHU reduction and subsequent reaction with RNH 2-containing compounds is important for the work reported below on characterizing fluorescent-labeled tRNAs.Earlier studies of NaBH 4 reduction of DHU reported two different products for reactions carried out under different conditions

ChEBI. 5,6-Dihydrouridine (Dihydrouridine) is one of the posttranscriptionally modified nucleosides. It is a product of the reduction of uridine (U), and can be further modified to 5-methyldihydrouridine (m5D). 5,6-Dihydrouridine is commonly present in the tRNA from Bacteria, Eukaryota, and some Archaea Dihydrouridine synthases (Dus) from different subfamilies selectively reduce distinct uridines, located at spatially unique positions of folded tRNA, into dihydrouridine. Because the catalytic center of all Dus enzymes is conserved, it is unclear how the same protein fold can be reprogrammed to ensure that nucleotides exposed at spatially distinct faces of tRNA can be accommodated in the same.
