Characterization of the plasmid pMB1 from Bifidobacterium longum and its use for shuttle vector construction.
The nucleotide sequence of the 1847-bp Bifidobacterium longum B2577 cryptic plasmid pMB1 was determined. The plasmid had a G+C content of 62.0%, and contained two open reading frames, orf1 and orf2, likely arranged in an operon. The proteins encoded by orf1 and orf2 show the highest degree of similarity with similarly arranged peptide sequences translated from Corynebacterium glutamicum pXZ1014...
متن کاملCharacterization of a small cryptic plasmid from endophytic Pantoea agglomerans and its use in the construction of an expression vector
A circular cryptic plasmid named pPAGA (2,734 bp) was isolated from Pantoea agglomerans strain EGE6 (an endophytic bacterial isolate from eucalyptus). Sequence analysis revealed that the plasmid has a G+C content of 51% and contains four potential ORFs, 238(A), 250(B), 131(C), and 129(D) amino acids in length without homology to known proteins. The shuttle vector pLGM1 was constructed by combin...
متن کاملConstruction and characterization of a highly efficient Francisella shuttle plasmid.
Francisella tularensis is a facultative intracellular pathogen that infects a wide variety of mammals and causes tularemia in humans. It is recognized as a potential agent of bioterrorism due to its low infectious dose and multiple routes of transmission. To date, genetic manipulation in Francisella spp. has been limited due to the inefficiency of DNA transformation, the relative lack of useful...
متن کاملConstruction and characterization of a replication-competent retroviral shuttle vector plasmid.
We constructed two versions of an RCASBP-based retroviral shuttle vector, RSVP (RCASBP shuttle vector plasmid), containing either the zeocin or blasticidin resistance gene. In this vector, the drug resistance gene is expressed in avian cells from the long terminal repeat (LTR) promoter, whereas in bacteria the resistance gene is expressed from a bacterial promoter. The vector contains a bacteri...
متن کاملReduction of technetium by Desulfovibrio desulfuricans: biocatalyst characterization and use in a flowthrough bioreactor.
Resting cells of Desulfovibrio desulfuricans coupled the oxidation of a range of electron donors to Tc(VII) reduction. The reduced technetium was precipitated as an insoluble low-valence oxide. The optimum electron donor for the biotransformation was hydrogen, although rapid rates of reduction were also supported when formate or pyruvate was supplied to the cells. Technetium reduction was less ...
