Common evolutionary origin of the ilvGMEDA attenuation locus and tRNA(1Leu) in Escherichia coli.
Published sequences of transcripts from ilvGMEDA leader regions of several enteric bacteria were compared with published sequences of the tRNAs from Escherichia coli. The analyses revealed homology between the ilvGMEDA leader peptide-coding region and tRNA(1Leu) in E. coli, Salmonella typhimurium, and Klebsiella aerogenes, whereas homology was not present in Serratia marcescens and Edwardsiella tarda.
