Intergeneric conjugation between Escherichia coli and Streptomyces species.
We have constructed Escherichia coli-Streptomyces shuttle plasmids which are capable of conjugal transfer from E. coli to Streptomyces spp. These plasmids contained the pBR322 and pIJ101 origins of replication and the RK2 (IncP) origin of transfer. The transfer of plasmid was specifically dependent the presence of a 760-base-pair, cis-acting, oriT-containing fragment and on RP4 (IncP) functions...
متن کاملAn Efficient Intergeneric Conjugation of DNA from Escherichia coli to Mycelia of the Lincomycin-Producer Streptomyces lincolnensis
Streptomyces lincolnensis is a producer of lincomycin, which is a lincosamide antibiotic for the treatment of infective diseases caused by Gram-positive bacteria. S. lincolnensis is refractory to introducing plasmid DNA into cells because of resistance of foreign DNAs and poor sporulation. In this study, a simple and efficient method of transferring plasmids into S. lincolnensis through the int...
متن کاملGeneration of biallelic knock-out sheep via gene-editing and somatic cell nuclear transfer
Transgenic sheep can be used to achieve genetic improvements in breeds and as an important large-animal model for biomedical research. In this study, we generated a TALEN plasmid specific for ovine MSTN and transfected it into fetal fibroblast cells of STH sheep. MSTN biallelic-KO somatic cells were selected as nuclear donor cells for SCNT. In total, cloned embryos were transferred into 37 reci...
متن کاملIdentification and Characterization of Mycemycin Biosynthetic Gene Clusters in Streptomyces olivaceus FXJ8.012 and Streptomyces sp. FXJ1.235
Mycemycins A-E are new members of the dibenzoxazepinone (DBP) family, derived from the gntR gene-disrupted deep sea strain Streptomyces olivaceus FXJ8.012Δ1741 and the soil strain Streptomyces sp. FXJ1.235. In this paper, we report the identification of the gene clusters and pathways' inference for mycemycin biosynthesis in the two strains. Bioinformatics analyses of the genome sequences of S. ...
متن کاملChanges in liver gene expression of Azin1 knock-out mice.
The ornithine decarboxylase antizyme inhibitor (AZI) was discovered as a protein that binds to the regulatory protein antizyme and inhibits the ability of antizyme to interact with the enzyme ornithine decarboxylase (ODC). Several studies showed that the AZI protein is important for cell growth in vitro. However, the function of this gene in vivo remained unclear. In our study, we analyzed the ...
