Mapping of the 5-methyltryptophan resistance locus in Bacillus subtilis.
The 5-methyltryptophan resistance locus (mtr) in Bacillus subtilis, which leads to constitutive production of the tryptophan enzymes, has been mapped on the chromosome. The order of loci is ser-1-mtr-aroF-aroB-trp-hisB.
متن کاملControl of tryptophan biosynthesis by the methyltryptophan resistance gene in Bacillus subtilis.
5-Methyltryptophan-resistant mutants derived from Bacillus subtilis strain 168 synthesize all of the tryptophan biosynthetic enzymes constitutively and excrete tryptophan. These mutants can be divided into three classes: class 1, low enzyme level and low rate of tryptophan excretion; class 2, high enzyme level and intermediate rate of tryptophan excretion; and class 3, high enzyme level and hig...
متن کاملCharacterization of the Bacillus subtilis tryptophan promoter region.
The nucleotide sequence of the control region of the trp operon of Bacillus subtilis has been determined. The region was shown to contain the trp promoter by deletion analysis and by determination of the transcription start site. The trp promoter shows similarity to the consensus sequence for Escherichia coli and B. subtilis promoters. The presence of the trp control region on a high-copy-numbe...
متن کاملAntimetabolite action of 5-methyltryptophan in Bacillus subtilis.
The roles of anthranilate and histidine in the regulation of tryptophan synthesis were implicated by observations of antagonistic relationships with 5-methyltryptophan in Bacillus subtilis.
متن کاملPhysical and genetic mapping of the SPO2 prophage on the chromosome of Bacillus subtilis 168.
It has been found by density transfer and genetic mapping experiments that prophage SPO2 is linked to the antibiotic resistance marker ery-1 in Bacillus subtilis 168.
