A new Thermus-Escherichia coli shuttle integration vector system.
We established a Thermus thermophilus strain in which the pyrE gene (coding for orotate phosphoribosyltransferase of the pyrimidine biosynthetic pathway) was totally deleted. We also constructed an integration vector, which consisted of the Escherichia coli plasmid vector pBluescript and a 2.1-kb segment of the T. thermophilus leu operon sequence, for the integration of a foreign gene into a ch...
متن کاملNew shuttle vector-based expression system to generate polyhistidine-tagged fusion proteins in Staphylococcus aureus and Escherichia coli.
Four Staphylococcus aureus-Escherichia coli shuttle vectors were constructed for gene expression and production of tagged fusion proteins. Vectors pBUS1-HC and pTSSCm have no promoter upstream of the multiple cloning site (MCS), and this allows study of genes under the control of their native promoters, and pBUS1-Pcap-HC and pTSSCm-Pcap contain the strong constitutive promoter of S. aureus type...
متن کاملConstruction of a genetically engineered microorganism for CO2 fixation using a Rhodopseudomonas/Escherichia coli shuttle vector.
The CO2 fixation ability of Rhodopseudomonas palustris DH was enhanced by introducing the recombinant plasmid pMG-CBBM containing the form II ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) gene (cbbM) isolated from Rps. palustris NO. 7. Sequencing of a 3.0-kb PstI fragment containing the cbbM gene revealed an open reading frame encoding 461 amino acids, homologous to known cbbM genes...
متن کاملConstruction of a Shuttle Vector for Heterologous Gene Expression in Escherichia coli and Microalgae Anabaena
The construction of an integrative shuttle expression vector and potential utility was reported in Escherichia coli and Anabaena (Nostoc) sp. strain PCC 7120. The vector comprised of the following elements: (a) an intergenic non-coding region from Anabaena to facilitate its genomic integration (b) a strong functional PpsbAI promoter from Anabaena for desired gene expression and (c) neomycin pho...
متن کاملConstruction of a Helicobacter pylori-Escherichia coli shuttle vector for gene transfer in Helicobacter pylori.
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 jeju...
