Chloramphenicol-inducible gene expression in Bacillus subtilis - Duvall, E.J.; Williams, D.M.; Lovett, P.S.; Rudolph, C.; Vasantha, N.; Guyer, M. (Elsevier)
A cloned Bacillus pumilus cat gene expresses chloramphenicol-inducible chloramphenicol acetyltransferase activity in Bacillus subtilis. The chloramphenicol inducibility trait was shown to be determined by a 234-bp region of the cloned DNA. Nucleotide sequence analysis of this 234-bp segment indicated that the cat ribosome-binding site occurs within a 40-bp region containing 14-bp terminal inverted repeat sequences. Transcription of this region into RNA should sequester the cat ribosome-binding site in a stable stem-loop conformation. Chloramphenicol-mediated destabilization of the stem-loop is suggested as the basis for the chloramphenicol inducibility phenotype.
