Isolation of a strong suppressor of nonsense mutations in Bacillus subtilis.

چکیده
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 isolated, being suppressed by both the su+3 and su+44 suppressor strains. The efficiency of suppression by strain su+44 is about 50%. The experiments shown in this paper suggest that strain su+44 contains an amber and strain su+3 an ochre suppressor.

A suppressor of nonsense mutations in Bacillus subtilis.
The suppressor-sensitive mutants of phage 429, susB47 and susN212, do not induce the synthesis of proteins NP1 and 11, respectively, when they infect Bacillus subtilis su-. A new polypeptide of molecular weight 75000, smaller than that of protein NP1, is produced in susB47-infected cells. An analysis of the methionine-containing tryptic peptides of protein NP1 and the 75000-molecularweight poly...
متن کاملAnalysis of a suppressor mutation ssb (kinC) of sur0B20 (spo0A) mutation in Bacillus subtilis reveals that kinC encodes a histidine protein kinase.
sur0B20 is a mutation that suppresses the effects of spo0B delta B or spo0F221 mutations in Bacillus subtilis, sur0B20 is an allele of the spo0A gene (Glu-14 to Val-14 conversion) and restores the sporulation of spo0B or spo0F mutants to the wild-type level. Here, we report the isolation of suppressor mutations of sur0B20 (ssb). One of these mutations, ssb-12, severely impairs the suppressor ac...
متن کاملIsolation and sequence of ctaA, a gene required for cytochrome aa3 biosynthesis and sporulation in Bacillus subtilis.
Cytochrome aa3 is one of two terminal oxidase complexes in the Bacillus subtilis electron transport chain. A novel genetic strategy was devised which permitted the isolation of B. subtilis mutants lacking cytochrome aa3 by selection for streptomycin-resistant clones which failed to oxidize the artificial electron donor N,N,N',N'-tetramethyl-p-phenylenediamine. Two mutations were studied intensi...
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.

The goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native Iranian microorganisms. At the end of screening program, a Bacillus subtilis BP-36 strain producing thermophilic alkaline protease was isolated from a hot spring in Ardebil province. The target enzyme was purified using a one-step Aqueous two-phase systems (ATPS) prot...
