Abstract
Guanylation of tRNA by a lysate of rabbit reticulocytes was reported previously by Farkas and Singh. This reaction was investigated further using 18 purified E. coli tRNAs as acceptors. Results showed that only tRNATyr, tRNAHis, tRNAAsn and tRNAAsP which contain the modified nucleoside Q in the anticodon acted as acceptors. Analysis of the nucleotide sequences in the guanylated tRNA showed that guanine specifically replaced Q base in these tRNAs.Keywords
