| Abstract | A Bacillus licheniformis ATCC31667 gene coding for a glucose isomerase has been cloned and expressed in glucose isomerase negative mutant of Escherichia coli. A recombinant plasmid, constructed by ligation of a EcoRI fragment of B.licheniformis chromosomal DNA to vector plasmid pBR322, was expressed glucose isomerase positive in E.coli LE392-6 with growth on minimal medium containing xylose as a sole carbon source. This recombinant plasmid, designated pBGI6, had the insert of 4.1Kb of Bacillus gene in EcoRI site, and restriction map of the plasmid was established. The plasmid pBG16 was very stable after 10days of serial transfer to a fresh medium. The activity of glucose isomerase from the transformed cell containing pBGI6 was increased about 20 fold than its wild type of host. | ||
