عنوان انگلیسی Molecular cloning of gluconobacter oxydans DSM 2003 xylitol dehydrogenase gene
چکیده انگلیسی مقاله Due to the widespread applications of xylitol dehydrogenase, an enzyme used for the production of xylitol, the present study was designed for the cloning of xylitol dehydrogenase gene from Glcunobacter oxydans DSM 2003. After extraction of genomic DNA from this bacterium, xylitol dehydrogenase gene was replicated using polymerase chain reaction (PCR). The amplified product was entered into pTZ57R cloning vector by T/A cloning method and transformation was performed by heat shocking of the E. coli XL1-blue competent cells. Following plasmid preparation, the cloned gene was digested out and ligated into the expression vector pET-22b(+). Electrophoresis of PCR product showed a 789 bp band. Recombinant plasmid (rpTZ57R) was then constructed. This plasmid was double digested with XhoI and EcoRI resulting in 800 bp and 2900 bp bands. The obtained insert was ligated into pET-22b(+) vector and its orientation was confirmed with Xho I and Bam HI restriction enzymes. In conclusion, in the present study the recombinant expression vector containing xylitol dehydrogenase gene has been constructed and can be used for the production of this enzyme in high quantities.
