Abstract

We have identified the cis isomer of N6-(4-hydroxy-isopentenyl)-2-methylthioadenosine (ms2io6A) as a component of the tRNA of Salmonella typhimurium. This is the first report of this compound in the tRNA of any member of the enterobacteriaceae: the nucleoside was previously thought to be found exclusively in plants or plant associated bacteria. Interestingly, all E. coli strains examined were found to lack ms2io6A. Evidence is presented which suggests S. typhimurium tRNA also contains low levels of 5-carboxymethylaminomethyl-2-thiouridine (cmnm5s2U) in addition to 5-methylaminomethyl-2-thiouridine (mnm5s2U).
