Abstract excerpt

To elucidate the sequence elements required in the anticodon stem for the recognition of Escherichia coli tRNA(Ser) (GGA) by the E. coli isopentenyl-tRNA:A37 transferase (IPTT), which result in the conversion of A37 into isopentenylated i6A37, we have tested and characterized in vitro T7-runoff transcripts of 17 variants of E. coli tRNA(Ser)(GGA) and 7 other tRNAs from E. coli and yeast. Our results indicate...
