Transduction in Bacillus subtilis by bacteriophage SPP1.
Lysates of the virulent bacteriophage SPP1 were shown to be capable of mediating generalized transduction. Suppressible mutants of this bacteriophage (sus) were capable of transduction at a lower multiplicity of infection than virulent SPP1. Linkage analysis demonstrated that bacteriophage SPP1 transduced segments of the genome equal in size to that transferred by SP10. This bacteriophage shoul...
متن کاملRole of Erf recombinase in P22-mediated plasmid transduction.
In the absence of host RecA function, plasmid transduction by bacteriophage P22 can be mediated by Erf recombinase. Erf is not carried on the infecting particle but synthesized upon infection. In the recipient cell, Erf can promote both generalized plasmid transduction (which requires the circularization of plasmids transduced as linear multimers) and specialized plasmid transduction (which req...
متن کاملThe generation of concatemeric plasmid DNA in Bacillus subtilis as a consequence of bacteriophage SPP1 infection.
Bacteriophage SPP1 infection of Bacillus subtilis cells bearing plasmids induces the synthesis of multigenome-length plasmid molecules. Two independent pathways can account for this synthesis. In one of those, homology to the phage genome is required, whereas in the other such homology is not a prerequisite. In wild type cells both modes overlap. In dnaB(Ts), at non permissive temperature, or i...
متن کاملBioShuttle-mediated Plasmid Transfer
An efficient gene transfer into target tissues and cells is needed for safe and effective treatment of genetic diseases like cancer. In this paper, we describe the development of a transport system and show its ability for transporting plasmids. This non-viral peptide-based BioShuttle-mediated transfer system consists of a nuclear localization address sequence realizing the delivery of the plas...
متن کاملPlasmid mediated antibiotic resistance
Enterobacteriaceae is a family of bacteria including Escherichia coli and Klebsiella pneumoniae that are common colonizers of the gastrointestinal tract. Extended spectrum βlactamases (ESBL) are bacterial enzymes that degrade β-lactam antibiotics and thus make the bacteria resistant to β-lactam antibiotics. ESBL-producing Enterobacteriaceae (EPE) is an increasing problem constituting a burden o...
