generation of trmL+ and trmL- PBAD-rpoS990-lacZ translational fusions (in rssB- backgrounds) cells, executed for PBAD-rpoS990-lacZ translational fusions with rpoS UUA-Leu CUX-Leu mutations (leu*1)-strains KMT36002 and KMT36010, for rpoS UUG-Leu to CUX-leu mutation (leu*2)-strains KMT37002 and KMT37010, and for rpoS with both UUA-Leu to CUX-Leu and UUG-Leu to CUX-Leu mutations (leu*3)-strains KMT33001 and KMT33013, overview. Comparison of expression of PBAD-rpoS990-lacZ translational fusions carrying wild-type UUX leucine codons with derivatives in which UUX codons are changed to CUX codons, in the presence and absence of TrmL or TusA. The absence of these proteins, and therefore presumably the modifications they catalyze, both abolish PBAD-rpoS990-lacZ translation activity. UUX-Leu to CUX-Leu codon mutations in rpoS suppress the trmL requirement for PBAD-rpoS990-lacZ expression |
