SYSTEM AND METHODS FOR DETECTING RIBOSOME INHIBITION

摘要

This disclosure describes a cell genetically modified to detect ribosome inhibition in the cell and methods involving such a cell. Generally, the genetically-modified cell includes an aminoglycoside-sensitive orthogonal 16S rRNA (O-16S) coding region bearing a mutated anti- Shine-Dalgarno (O-ASD) sequence, a repressor/operator system, and a polynucleotide encoding a detectable reporter under transcriptional control of the repressor/operator system. The repressor/operator system includes a coding region that encodes a transcriptional regulator and having an orthogonal SD (O-SD) sequence complementary to the 16S rRNA O-ASD sequence. The operator sequence, which is repressable by the transcriptional regulator, is operably linked to the polynucleotide encoding a detectable reporter.
