Isolation of glutamate-inserting ochre suppressor mutants of Salmonella typhimurium and Escherichia coli.
Glutamate-inserting ochre suppressors have been identified among late-arising, spontaneous revertants of a hisG428 mutant of Salmonella typhimurium and an argE3 mutant of Escherichia coli. The S. typhimurium suppressors mapped in the tRNA2(Glu) gene gltU at 82 min; those in E. coli were found to be in tRNA2(Glu) genes gltW at 56 min, gltU at 85 min, and gltT at 90 min.
