Common Nameepoxyqueuosine
DescriptionEpoxyqueuosine is an intermediate in queosine biosynthesis. Queuosine is an important 7-deazapurine-modified nucleoside that is present in certain tRNAs in bacteria and most eukaryotes. Eposyqueosiine is a subsstrate for Epoxyqueuosine reductase catalyzes the final step in the de novo synthesis of queuosine, the anticodon loop modification found in tRNA(Asp), tRNA(Asn), tRNA(His), and tRNA(Tyr)
