Metabolite Identification
Common Name2-Thiouridine
Description2-thiouridine is a member of the chemical class known as Pyrimidine Nucleosides and Analogues. These are compounds comprising a pyrimidine base attached to a sugar. 2-thiouridine is invovled in tRNA-s2U34 biosynthesis. Thionucleosides are uniquely present in tRNA. In many organisms, tRNA specific for Lys, Glu, and Gln contain hypermodified 2-thiouridine (s(2)U) derivatives at wobble position 34. The s(2) group of s(2)U34 stabilizes anticodon structure, confers ribosome binding ability to tRNA and improves reading frame maintenance. [PMID:12549933 ]
