| | 4-THIOURIDINE Usage And Synthesis |
| Description | 4-Thiouridine (4-SU) is a photoactivatable ribonucleoside analog that is widely used for RNA analysis, including short-range RNA-RNA crosslinking and nascent RNA labeling. The crosslinking thio moiety is attached directly to the nucleotide base, thus 4-SU differs from uridine only by a single sulfur substitution. This offers the advantage of incorporating into an RNA chain with minimal structural perturbation and with similar base-pairing properties, reducing the likelihood that substitution will impair RNA interactions or activities. | | Uses | Nucleotide analogue, essential for cell growth in certain bacterial species. This compound is also able to chelate with certain metal ions, and in tRNA it can act as a built-in antiphotomutagenic agent that protects Escherichia coli cells against mutagenesis. | | Uses | 4-Thiouridine is a constituent of several transfer RNA's. 4-Thiouridine is a thionucleobase used as an antisense agent. Widely used for RNA analysis including RNA-RNA cross coupling and RNA labelling. 4-Thiouridine is a photoreactive (crosslinking) uridine analogue that upon phosphorylation to 4-thioUTP may be incorporated into RNA structures. 4-Thiouridine may be used to study the specificity and kinetics of uridine-cytidine kinases. 4-Thio Uridine is typically used to modify oligos slated for RNA, or RNA-protein, structural studies. A 4-thio-rU modified RNA pentamer was used to study the effect of this modification on codon-anticodon interaction when it is in the wobble position of tRNA. | | Definition | ChEBI: A thiouridine in which the oxygen replaced by sulfur is that at C-4. | | General Description | 4-Thiouridine is a photoreactive uridine analog. | | Biochem/physiol Actions | 4-Thiouridine plays a role in assessing nascent RNA synthesis. It also enhances site-specific crosslinking. 4-Thiouridine also acts as a photoaffinity probe due to its stability even while lacking specific photoactivation. It can also be incorporated into RNAs. | | storage | Store at -20°C |
