abstract = {It is long known that Kasugamycin inhibits translation of
canonical transcripts containing a 5’-UTR with a Shine
Dalgarno (SD) motif, but not that of leaderless transcripts.
To gain a global overview of the influence of Kasugamycin on
translation efficiencies, the changes of the translatome of
Escherichia coli induced by a 10 minutes Kasugamycin
treatment were quantified. The effect of Kasugamycin
differed widely, 102 transcripts were at least twofold more
sensitive to Kasugamycin than average, and 137 transcripts
were at least twofold more resistant, and there was a more
than 100-fold difference between the most resistant and the
most sensitive transcript. The 5’-ends of 19 transcripts
were determined from treated and untreated cultures, but
Kasugamycin resistance did neither correlate with the
presence or absence of a SD motif, nor with differences in
5’-UTR lengths or GC content. RNA Structure Logos were
generated for the 102 Kasugamycin-sensitive and for the 137
resistant transcripts. For both groups a short Shine
Dalgarno (SD) motif was retrieved, but no specific motifs
associated with resistance or sensitivity could be found.
Notably, this was also true for the region -3 to -1 upstream
of the start codon and the presence of an extended SD motif,
which had been proposed to result in Kasugamycin resistance.
Comparison of the translatome results with the database
RegulonDB showed that the transcript with the highest
resistance was leaderless, but no further leaderless
transcripts were among the resistant transcripts.
Unexpectedly, it was found that translational coupling might
be a novel feature that is associated with Kasugamycin
resistance. Taken together, Kasugamycin has a profound
effect on translational efficiencies of E. coli transcripts,
but the mechanism of action is different than previously
described.},
