mazF, a novel counter-selectable marker for unmarked chromosomal manipulation in Bacillus subtilis
Here, we present a novel method for the directed genetic manipulation of the Bacillus subtilis chromosome free of any selection marker. Our new approach employed the Escherichia coli toxin gene mazF as a counter-selectable marker. The mazF gene was placed under the control of an isopropyl-beta-D-thiogalactopyranoside (IPTG)-inducible expression system and associated with a spectomycin-resistanc...
متن کاملCounter-selectable marker for bacterial-based interaction trap systems.
Counter-selectable markers can be used in two-hybrid systems to search libraries for a protein or compound that interferes with a macromolecular interaction or to identify macromolecules from a population that cannot mediate a particular interaction. In this report, we describe the adaptation of the yeast URA3/5-FOA counter-selection system for use in bacterial interaction trap experiments. Two...
متن کاملRecombineering with tolC as a Selectable/Counter-selectable Marker: remodeling the rRNA Operons of Escherichia coli
This work describes the novel use of tolC as a selectable/counter-selectable marker for the facile modification of DNA in Escherichia coli. Expression of TolC (an outer membrane protein) confers relative resistance to toxic small molecules, while its absence renders the cell tolerant to colicin E1. These features, coupled with the lambdaredgam recombination system, allow for selection of tolC i...
متن کاملChromosomal insertions of Tn917 in Bacillus subtilis.
We describe 46 insertions of the Streptococcus faecalis transposon Tn917 into the chromosome of Bacillus subtilis. These insertion mutations were mapped genetically. Some caused auxotrophic requirements, and others were cryptic. These insertions were scattered around the B. subtilis chromosome. The mutant strains were useful in several ways for mapping and cloning B. subtilis genes and were add...
متن کاملMob/oriT, a mobilizable site-specific recombination system for unmarked genetic manipulation in Bacillus thuringiensis and Bacillus cereus
BACKGROUND Bacillus thuringiensis and Bacillus cereus are two important species in B. cereus group. The intensive study of these strains at the molecular level and construction of genetically modified bacteria requires the development of efficient genetic tools. To insert genes into or delete genes from bacterial chromosomes, marker-less manipulation methods were employed. RESULTS We present ...
