Characterization of Bacillus subtilis clones surviving overproduction of Zeta, a pSM19035 plasmid-encoded toxin.

چکیده
The postsegregational killing system of pSM19035 plasmid consists of the proteins Zeta and Epsilon, a toxin and an antidote, respectively. Zeta mutants were isolated with the use of Bacillus subtilis strain with the zeta gene under control of an inducible promoter integrated into the chromosome. Results of mutant analysis point to the amino terminal part of the Zeta protein as being responsible for the toxicity.

Characterization of a Novel Partition System Encoded by the and Genes from the Streptococcal Plasmid pSM19035
High segregational stability of the streptococcal plasmid pSM19035 is achieved by the concerted action of systems involved in plasmid copy number control, multimer resolution, and postsegregational killing. In this study, we demonstrate the role of two genes, and , in plasmid stabilization by a partition mechanism. We show that these two genes can stabilize the native pSM19035 replicon as well ...
متن کاملPlasmid copy-number control and better-than-random segregation genes of pSM19035 share a common regulator.
Transcription initiation of the copy-number control and better-than-random segregation genes of the broad-host-range and low-copy-number plasmid pSM19035 are subjected to repression by the autoregulated pSM19035-encoded omega product in Bacillus subtilis cells. The promoters of the copS (Pcop1 and Pcop2), delta (Pdelta), and omega (Pomega) genes have been mapped. These promoters are embedded in...
متن کاملIn vivo interactions between toxin-antitoxin proteins epsilon and zeta of streptococcal plasmid pSM19035 in Saccharomyces cerevisiae.
The widespread prokaryotic toxin-antitoxin (TA) systems involve conditional interaction between two TA proteins. The interaction between the Epsilon and Zeta proteins, constituting the TA system of plasmid pSM19035 from Streptococcus pyogenes, was detected in vivo using a yeast two-hybrid system. As we showed using Saccharomyces cerevisiae, the Zeta toxin hybrid gene also exerts its toxic effec...

Bacillus anthracis Sterne cured of the pXO1 plasmid had enhanced secreted protease activity during the postexponential phase but no change in hemolytic or lecithinase activities. A zymogen profile revealed at least six proteases, including serine, metal, and perhaps cysteine types. There were similar amounts of protease secreted by the closely related species Bacillus cereus and Bacillus thurin...

In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...
