5-Aminomethyl-2-thiouridine or mnm5s2U, is naturally occurring modified nucleoside present in tRNA that has been studied in E. coli via the activity of tRNA (5-methylaminomethyl-2-thiouridine)-methyltransferase

ChEBI:5-aminomethyl-2-thiouridine is a nucleoside analogue having 5-aminomethyl-2-thiouracil as the modified nucleobase. It is functionally related to a uridine. It is a conjugate base of a 5-aminomethyl-2-thiouridine(1+).
