Abstract
Here we report on the construction of two integrative plasmids for Bacillus subtilis allowing in vitro construction of translational fusions. Both plasmids contain two cassettes in tandem: the bgaB gene encoding a heat-stable beta-galactosidase devoid of its own regulatory sequences and the first two codons followed by a neomycin-resistance gene for selection in B. subtilis. Both cassettes are flanked by the 3'- and 5'-end of the amyE gene (encoding alpha-amylase) allowing integration of both cassettes at the amyE locus of the B. subtilis chromosome. For propagation in Escherichia coli, the plasmids contain the pBR322 origin of DNA replication and the beta-lactamase-encoding gene. Whereas one vector needs a promoter, a Shine-Dalgarno sequence and the beginning of a gene fused in-frame to bgaB, the other one already carries a constitutive promoter. The versatility of the gene fusion vectors was demonstrated by the integration of the regulatory regions of the dnaK and the cat-86 genes. In the first case, heat-inducible expression was found, and by comparison with an operon fusion, it seems that the dnaK operon is regulated at both the transcriptional and the posttranscriptional level. In the second case, chloramphenicol-inducible...Continue Reading
