Mini-mu bacteriophage with plasmid replicons for in vivo cloning and lac gene fusing.
New mini-Mu transposons with plasmid replicons were constructed with additional features for in vivo DNA cloning and lac gene fusing in Escherichia coli. These mini-Mu replicons can be used to clone DNA by growing them with a complementing Mu bacteriophage and by using the resulting lysate to transduce Mu-lysogenic cells. These mini-Mu phage have selectable genes for resistance to kanamycin, ch...
متن کاملCloning of the A gene of bacteriophage Mu and purification of its product, the Mu transposase.
The bacteriophage Mu transposase (the Mu A gene product), which is absolutely required for both integration of Mu and replicative transposition during the lytic cycle, has been overproduced by cloning the gene on a plasmid under the control of the phage lambda PL promoter. The protein has been purified to near homogeneity from the lysate of heat-induced cells of a strain carrying the plasmid. T...

متن کاملParticipation of the lytic replicon in bacteriophage P1 plasmid maintenance.
P1 bacteriophage carries at least two replicons: a plasmid replicon and a viral lytic replicon. Since the isolated plasmid replicon can maintain itself stably at the low copy number characteristic of intact P1 prophage, it has been assumed that this replicon is responsible for driving prophage replication. We provide evidence that when replication from the plasmid replicon is prevented, prophag...
متن کاملDesign and Construction of a Cloning Vector Containing the hspX Gene of Mycobacterium tuberculosis
Background: Tuberculosis (TB) is a major cause of death worldwide. Finding an effective vaccine against TB is the best way to control it. Several vaccines against this disease have been developed but none are completely protective. The aim of this study was to design and construct a cloning vector containing the Mycobacterium tuberculosis (M. tuberculosis) heat shock protein X (hspX). Metho...
