Eukaryotic promoters drive gene expression in Escherichia coli.
Eight eukaryotic promoters have been tested for their activity in vivo in Escherichia coli. The rat beta-actin, rat amylase, rat chymotrypsin B, mouse metallothionein I, rat insulin I, human insulin, Rous sarcoma virus long terminal repeat (RSV LTR) and hepatitis B viral precore promoter activities were measured by using the bacterial chloramphenicol acetyltransferase coding sequences as the re...
متن کاملExpression of Eukaryotic Gene in E. coli
Gene expression is the process by which inheritable information from a gene, such as the DNA sequence, is made into a functional gene product, such as protein or RNA. Several steps in the gene expression process may be modulated, including the transcription step and translation step and the post-translational modification of a protein. A wide range of microorganisms produce invertase and can, t...
متن کاملCONSTRUCTION OF RECOMBINANT PLASMIDS FOR PERIPLASMIC EXPRESSION OF HUMAN GROWTH HORMONE IN ESCHERICHIA COLI UNDER T7 AND LAC PROMOTERS
In order to study the periplasmic expression of human growth hormone (hGH) in Escherichia coli, the related cDNA was inserted in two expression plasmids carrying pelB signal peptide, one with lac bacterial promoter and the other with a bacteriophage T7-based promoter. The recombinant plasmids were moved to TG1 and BL21 strains of E. coli, respectively. To induce the expression systems, IPTG and...
متن کاملFunctional genetic expression of eukaryotic DNA in Escherichia coli.
We have isolated a segment of DNA from the eukaryote Saccharomyces cerevisiae (baker's yeast) as a viable molecular hybrid of bacteriophage lambda DNA which, when integrated into the chromosome of an E. coli histidine auxotroph, allows this bacterium to grow in the absence of histidine. The nonrevertable, histidine auxotroph lacks the enzymatic activity of imidazole glycerol phosphate (IGP) deh...
متن کاملConsensus sequence for Escherichia coli heat shock gene promoters.
We have identified promoters for the Escherichia coli heat shock operons dnaK and groE and the gene encoding heat shock protein C62.5. Transcription from each promoter is heat-inducible in vivo, and each is recognized in vitro by RNA polymerase containing sigma 32, the sigma factor encoded by rpoH (htpR) but not by RNA polymerase containing sigma 70. We compared the sequences of the heat shock ...
