The ars operon in the skin element of Bacillus subtilis confers resistance to arsenate and arsenite.
The Bacillus subtilis skin element confers resistance to arsenate and arsenite. The ars operon in the skin element contains four genes in the order arsR, ORF2, arsB, and arsC. Three of these genes are homologous to the arsR, arsB, and arsC genes from the staphylococcal plasmid pI258, while no homologs of ORF2 have been found. Inactivation of arsR, arsB, or arsC results in either constitutive ex...
متن کاملA de novo protein confers copper resistance in Escherichia coli.
UNLABELLED To survive environmental challenges, biological systems rely on proteins that were selected by evolution to function in particular cellular and conditional settings. With the advent of protein design and synthetic biology, it is now possible to construct novel proteins that are not biased by eons of selection in natural hosts. The availability of these sequences prompts us to ask whe...
متن کاملMolecular Characterization and Antimicrobial Resistance of Uropathogenic Escherichia coli
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
متن کاملL-arabinose operon of Escherichia coli
TIG December 2000, volume 16, No. 12 559 Over forty years of research on the L-arabinose operon of Escherichia coli have provided insights into the mechanism of positive regulation of gene activity. This research also discovered DNA looping and the mechanism by which the regulatory protein changes its DNA-binding properties in response to the presence of arabinose. As is frequently seen in focu...
متن کاملIdentification of the metalloregulatory element of the plasmid-encoded arsenical resistance operon.
The regulatory region of the plasmid-encoded arsenical resistance (ars) operon was cloned as a 727-bp EcoRI-HindIII fragment. When cloned into a promoter probe vector this fragment conferred arsenite inducible tetracycline resistance in Escherichia coli, indicating that the fragment carried a regulatory gene, the arsR gene. A single region corresponding to -35 and -10 promoter recognition sites...
