Temperature sensitivity caused by mutant release factor 1 is suppressed by mutations that affect 16S rRNA maturation.

Abstract excerpt

To study the effect of slow termination on the protein synthesizing machinery, we isolated suppressors to a temperature-sensitive release factor 1 (RF1). Of 26 independent clones, five complementation groups have been identified, two of which are presented here. The first mutation disrupts a base pair in the transcription terminator stem for the rplM-rpsI operon, which encodes ribosomal proteins L13 and S9. We...
