The immunosuppressant mycophenolic acid inhibits an enzyme that acts on this molecule. Xanthorrhizol resistance is increased by TadA overexpression, which synthesizes this molecule in E. coli. By encouraging T-cell proliferation, this molecule’s pranobex is used as an antiviral. This molecule’s monophosphate cyclohydrolase forms this molecule from FAICAR, where it is the first of three products to be formed in a de novo pathway that begins with the transfer of an amino group from glutamine onto PRPP. This molecule consists of (*) hypoxanthine bonded to a ribose ring and is formed by the deamination of adenosine, which is catalyzed (10[1])by ADAR enzymes in A-to-I editing. By forming two hydrogen bonds with cytosine, adenine, and uracil, this molecule contributes to the wobble (-5[1])effect. For 10 points, name this non-canonical (10[1])nucleoside found in tRNA. ■END■ (0[2])
