Functional analysis of pAL5000, a plasmid from Mycobacterium fortuitum: construction of a "mini" mycobacterium-Escherichia coli shuttle vector.

ABSTRACT: Functional domains of pAL5000 were determined by gene disruption and deletion analysis. Of the five plasmid open reading frames (ORFs), ORF1 to ORF5, and a putative origin of replication previously identified (J. Rauzier, J. Moniz-Pereira, and B. Gicquel-Sanzey, Gene 71:315-321), two of the ORFs (ORF3 and ORF4) were deemed dispensable for plasmid replication. A "mini" mycobacterium-Escherichia coli shuttle plasmid applicable for general recombinant DNA studies in mycobacteria was constructed by using the gene for Kanr (Tn903) as a selective marker. Heterologous expression of the gene for Kanr was confirmed by Western blotting (immunoblotting) analysis.

The development of a novel Mycobacterium-Escherichia coli shuttle vector system using pMyong2, a linear plasmid from Mycobacterium yongonense DSM 45126T.

Project description:The Mycobacterium-Escherichia coli shuttle vector system, equipped with the pAL5000 replicon, is widely used for heterologous gene expression and gene delivery in mycobacteria. Despite its extensive use, this system has certain limitations, which has led to the development of alternative mycobacterial vector systems. The present study describes the molecular structure and expression profiles of a novel 18-kb linear plasmid, pMyong2, from Mycobacterium yongonense. Sixteen open reading frames and a putative origin of replication were identified, and the compatibility of the pMyong2 and pAL5000 vector systems was demonstrated. In recombinant Mycobacterium smegmatis (rSmeg), the pMyong2 vector system showed a copy number that was approximately 37 times greater than that of pAL5000. Furthermore, pMyong2 increased the mRNA and protein expression of the human macrophage migration inhibitory factor (hMIF) over pAL5000 levels by approximately 10-fold and 50-fold, respectively, demonstrating the potential utility of the pMyong2 vector system in heterologous gene expression in mycobacteria. Successful delivery of the EGFP gene into mammalian cells via rSmeg carrying the pMyong2 vector system was also observed, demonstrating the feasibility of this system for DNA delivery. In conclusion, the pMyong2 vector system could be effectively used not only for the in vivo delivery of recombinant protein and DNA but also for mycobacterial genetic studies as an alternative or a complement to the pAL5000 vector system.

Construction and transformation of a Thermotoga-E. coli shuttle vector.

Project description:BACKGROUND: Thermotoga spp. are attractive candidates for producing biohydrogen, green chemicals, and thermostable enzymes. They may also serve as model systems for understanding life sustainability under hyperthermophilic conditions. A lack of genetic tools has hampered the investigation and application of these organisms. This study aims to develop a genetic transfer system for Thermotoga spp. RESULTS: Methods for preparing and handling Thermotoga solid cultures under aerobic conditions were optimized. A plating efficiency of ~50% was achieved when the bacterial cells were embedded in 0.3% Gelrite. A Thermotoga-E. coli shuttle vector pDH10 was constructed using pRQ7, a cryptic mini-plasmid found in T. sp. RQ7. Plasmid pDH10 was introduced to T. maritima and T. sp. RQ7 by electroporation and liposome-mediated transformation. Transformants were isolated, and the transformed kanamycin resistance gene (kan) was detected from the plasmid DNA extracts of the recombinant strains by PCR and was confirmed by restriction digestions. The transformed DNA was stably maintained in both Thermotoga and E. coli even without the selective pressure. CONCLUSIONS: Thermotoga are transformable by multiple means. Recombinant Thermotoga strains have been isolated for the first time. A heterologous kan gene is functionally expressed and stably maintained in Thermotoga.

Characterization of the basic replicon of Rhodococcus plasmid pSOX and development of a Rhodococcus-Escherichia coli shuttle vector.

Project description:The replication region of a 100-kb desulfurization plasmid (pSOX) from Rhodococcus sp. strain X309 was localized to a 4-kb KpnI fragment, and its sequence was determined. The amino acid sequence of one of the predicted open reading frames (ORFs) was related to the putative replication (Rep) protein sequences of the mycobacterial pLR7 family of plasmids. Three of the five predicted ORF products were identified by radiolabelling with the Escherichia coli T7 polymerase/promoter system. In E. coli, the Rep protein of pSOX was apparently synthesized in a shortened form, 21.3 kDa instead of the predicted 41.3 kDa, as a result of an internal initiation. This situation is reminescent of that for some bacterial Rep proteins. A shuttle plasmid was constructed with the pSOX origin, pBluescript II KS-, and the chloramphenicol resistance (Cmr) gene from pRF29. This new shuttle plasmid was used to demonstrate expression of the Bacillus subtilis sacB gene in a strain of Rhodococcus, rendering it sensitive to the presence of sucrose.

Construction of a Helicobacter pylori-Escherichia coli shuttle vector for gene transfer in Helicobacter pylori.

Project description:In this study, a Helicobacter pylori-Escherichia coli shuttle vector was constructed for transferring DNA into H. pylori. The smallest cryptic plasmid (1.2 kb), pHP489, among those harbored by 77 H. pylori isolates was selected as a base replicon for constructing vectors. HindIII-digested pHP489 was ligated with a kanamycin resistance gene [aph(3')-III], which originated from Campylobacter jejuni, to produce the recombinant plasmid pHP489K. pHP489K was efficiently transformed into and stably maintained in H. pylori strains. The shuttle vector pBHP489K (3.6 kb) was constructed by the recombination of pHP489, ColE1, and aph(3')-III sequences. pBHP489K was reciprocally transformed into and maintained in both H. pylori and E. coli. Introduction of the shuttle vector clone DNA (pBHP489K/AB; 6.7 kb), containing the ureA and ureB genes of H. pylori, into urease-negative mutants of H. pylori led to the restoration of their urease activity. The transformants were confirmed to contain the incoming plasmid DNA. pBHP489K satisfied the requirements for an H. pylori-E. coli shuttle vector, implying that it might be a useful vector for investigating pathogenicity and restriction-modification systems of H. pylori.

Construction of a Shuttle Vector Using an Endogenous Plasmid From the Cyanobacterium Synechocystis sp. PCC6803.

Project description:To advance synthetic biology in the photosynthetic cyanobacterium Synechocystis sp. PCC6803 (Syn6803), we constructed a shuttle vector with some versatile features. This shuttle vector, pSCB-YFP, consists of a putative replicon identified on the plasmid pCC5.2, the origin of replication of pMB1 from E. coli, as well as the YFP reporter gene and a spectinomycin/streptomycin resistance cassette. pSCB-YFP is stably maintained in Syn6803M (a motile strain that lacks the endogenous pCC5.2) and expresses YFP. In addition, we engineered a fragment into pSCB-YFP that has multiple cloning sites and other features such that this plasmid can also be used as an expression vector (pSCBe). The shuttle vector pSCB-YFP can be stably maintained for at least 50 generations without antibiotic selection. It is a high copy number plasmid and can stably co-exist with the RSF1010-based pPMQAK1-GFP.

Properties and construction of plasmid pFW213, a shuttle vector with the oral Streptococcus origin of replication.

Project description:Streptococcus parasanguinis is among the most successful colonizers of the human body. Strain FW213 harbors a 7.0-kb cryptic plasmid, pFW213, with a copy number at 5 to 10 per chromosome. Sequence and functional analyses of pFW213 revealed that the open reading frame (ORF) encoding the replication protein (Rep) is essential for the replication of pFW213, and the putative plasmid addiction system (RelB and RelE) and an ORF (ORF6) with no known function are required for its stability. The minimal replicon of pFW213 contains the rep gene and its 5'-flanking 390-bp region. Within the minimal replicon, an A/T-rich region followed by 5 contiguous 22-bp repeats was located 5' of the ATG of rep. No single-stranded replication intermediates were detected in the derivatives of pFW213, suggesting that pFW213 replicates via the theta replication mechanism. The minimal replicon was unstable in streptococcal hosts without selection, but the stability was greatly enhanced in derivatives containing the intact relBE genes. A Streptococcus-Escherichia coli shuttle vector, pCG1, was constructed with the pFW213 replicon. Plasmid pCG1 features a multiple cloning region and a spectinomycin resistance determinant that is expressed in both Streptococcus spp. and E. coli. Various streptococcal DNA fragments were cloned in pCG1, and the recombinant constructs were stably maintained in the streptococcal hosts. Since pCG1 is compatible with the most widely used streptococcal replicon, pVA380-1, pCG1 will provide a much needed tool allowing the cloning of two genes that work in concert in the same host.

Construction of a mini-RNA replicon in <i>Escherichia coli</i>.

Project description:How the ribonucleic acid (RNA) world transited to the deoxyribonucleic acid (DNA) world has remained controversial in evolutionary biology. At a certain time point in the transition from the RNA world to the DNA world, 'RNA replicons', in which RNAs produce proteins to replicate their coding RNA, and 'DNA replicons', in which DNAs produce RNA to synthesize proteins that replicate their coding DNA, can be assumed to coexist. The coexistent state of RNA replicons and DNA replicons is desired for experimental approaches to determine how the DNA world overtook the RNA world. We constructed a mini-RNA replicon in Escherichia coli. This mini-RNA replicon encoded the β subunit, one of the subunits of the Qβ replicase derived from the positive-sense single-stranded Qβ RNA phage and is replicated by the replicase in E. coli. To maintain the mini-RNA replicon persistently in E. coli cells, we employed a system of α complementation of LacZ that was dependent on the Qβ replicase, allowing the cells carrying the RNA replicon to grow in the lactose minimal medium selectively. The coexistent state of the mini-RNA replicon and DNA replicon (E. coli genome) was successively synthesized. The coexistent state can be used as a starting system to experimentally demonstrate the transition from the RNA-protein world to the DNA world, which will contribute to progress in the research field of the origin of life.

Characterization of a small plasmid from Desulfovibrio desulfuricans and its use for shuttle vector construction.

Project description:A 2.3-kb plasmid present in about 20 copies per genome was identified in extracts of Desulfovibrio desulfuricans G100A and designated pBG1. It appears to be unable to replicate in Escherichia coli. Although composite plasmids of pBG1 inserted into pTZ18U are stable in E. coli, few if any pBG1-specific transcripts are detectable. The plasmid sequence reveals several features typical of the origin of replication of non-ColE1 enterobacterial plasmids as well as several potential open reading frames. This small replicon has been shown to support the replication of recombinant plasmids in D. desulfuricans G100A and Desulfovibrio fructosovorans. A conjugable shuttle vector has been constructed.

Assembly of long DNA sequences using a new synthetic Escherichia coli-yeast shuttle vector.

Project description:Synthetic biology is a newly developed field of research focused on designing and rebuilding novel biomolecular components, circuits, and networks. Synthetic biology can also help understand biological principles and engineer complex artificial metabolic systems. DNA manipulation on a large genome-wide scale is an inevitable challenge, but a necessary tool for synthetic biology. To improve the methods used for the synthesis of long DNA fragments, here we constructed a novel shuttle vector named pGF (plasmid Genome Fast) for DNA assembly in vivo. The BAC plasmid pCC1BAC, which can accommodate large DNA molecules, was chosen as the backbone. The sequence of the yeast artificial chromosome (YAC) regulatory element CEN6-ARS4 was synthesized and inserted into the plasmid to enable it to replicate in yeast. The selection sequence HIS3, obtained by polymerase chain reaction (PCR) from the plasmid pBS313, was inserted for screening. This new synthetic shuttle vector can mediate the transformation-associated recombination (TAR) assembly of large DNA fragments in yeast, and the assembled products can be transformed into Escherichia coli for further amplification. We also conducted in vivo DNA assembly using pGF and yeast homologous recombination and constructed a 31-kb long DNA sequence from the cyanophage PP genome. Our findings show that this novel shuttle vector would be a useful tool for efficient genome-scale DNA reconstruction.

Characterization of plasmid pOR1 from Ornithobacterium rhinotracheale and construction of a shuttle plasmid.

Project description:The bacterium Ornithobacterium rhinotracheale has been recognized as an emerging pathogen in poultry since about 10 years ago. Knowledge of this bacterium and its mechanisms of virulence is still very limited. Here we report the development of a transformation system that enables genetic modification of O. rhinotracheale. The system is based on a cryptic plasmid, pOR1, that was derived from an O. rhinotracheale strain of serotype K. Sequencing indicated that the plasmid consisted of 14,787 nucleotides. Sequence analysis revealed one replication origin and several rep genes that control plasmid replication and copy number, respectively. In addition, pOR1 contains genes with similarity to a heavy-metal-transporting ATPase, a TonB-linked siderophore receptor, and a laccase. Reverse transcription-PCR demonstrated that these genes were transcribed. Other putative open reading frames exhibited similarities with a virulence-associated protein in Actinobacillus actinomycetemcomitans and a number of genes coding for proteins with unknown function. An Escherichia coli-O. rhinotracheale shuttle plasmid (pOREC1) was constructed by cloning the replication origin and rep genes from pOR1 and the cfxA gene from Bacteroides vulgatus, which codes for resistance to the antibiotic cefoxitin, into plasmid pGEM7 by using E. coli as a host. pOREC1 was electroporated into O. rhinotracheale and yielded cefoxitin-resistant transformants. The pOREC1 isolated from these transformants was reintroduced into E. coli, demonstrating that pOREC1 acts as an independent replicon in both E. coli and O. rhinotracheale, fulfilling the criteria for a shuttle plasmid that can be used for transformation, targeted mutagenesis, and the construction of defined attenuated vaccine strains.
