Inducible amber suppressor for Bacillus subtilis.
نویسندگان
چکیده
An amber suppressor variant of Bacillus subtilis tyrosyl-tRNA was constructed and placed under control of the isopropyl-beta-D-thiogalactopyranoside (IPTG)-inducible Pspac promoter. Addition of IPTG resulted in a 50-fold increase in the expression of an rpsD-lacZ fusion containing a UAG amber codon. This system permitted isolation of a conditional lethal mutant which required IPTG for growth.

Isolation of a strong suppressor of nonsense mutations in Bacillus subtilis.
By treatment of Bacillus subtilis MO-101-P spoA- met thr- su- with ethyl methanesulfonate, a strong suppressor strain of nonsense mutations, B. subtilis MO-101-P spoA- [met-]+thr- su+44, was isolated. This strain does not suppress phage phi 29 mutant susB47, selected on a B. subtilis strain containing the su+3 suppressor isolated by Georgopoulos. A revertant from this mutant, susB610, was isola...
متن کاملIsolation and characterization of Bacillus subtilis sigB operon mutations that suppress the loss of the negative regulator RsbX.
sigmaB, a transcription factor that controls the Bacillus subtilis general stress response regulon, is activated by either a drop in intracellular ATP or exposure to environmental stress. RsbX, one of seven sigmaB regulators (Rsb proteins) whose genes are cotranscribed with sigmaB, is a negative regulator in the stress-dependent activation pathway. To better define the interactions that take pl...
متن کاملIsolation and properties of suppressor-sensitive mutants of Bacillus subtilis bacteriophage SP02.
Suppressor-sensitive mutants of Bacillus subtilis phage SPO2 were isolated and classified into 18 cistrons. A linear genetic map was constructed. The genes controlling early functions of phage development were clustered near the CI gene which may produce phage repressor.
متن کاملSuppressor system in Bacillus subtilis 168.
Multiple auxotrophic strains of Bacillus subtilis 168 were tested for joint one-step reversion of two or more auxotrophic markers to the wild-type phenotype. Mu8u5u5, a strain requiring leucine, methionine, and threonine, yielded revertants that grew without added methionine or threonine and proved to have a suppressor gene. When transferred by transformation with deoxyribonucleic acid, this su...
متن کاملHeat-inducible translational coupling in Bacillus subtilis.
Bacillus subtilis plasmid pGR71 is a promoter-probe shuttle vector derived from pUB110. The expression of the cat gene on pGR71 in B. subtilis requires the insertion of a Bacillus promoter and a ribosomal binding site (RBS) into the HindIII cloning site immediately upstream from the cat gene. A recombinant plasmid of pGR71, named pGR71-369, was obtained by a spontaneous deletion of a fragment c...
