Abstract
Abstract Novel chemical compounds, recombinant plasmids pUC1019 and pUC-1020, which are obtained by covalent linkage of ca. 4.2 kb BclI restriction endonuclease fragment of the Streptomyces espinosus plasmid pUC6 into the BamHI endonuclease site of the E. coli plasmid pBR322. Plasmid pUC1024 is obtained by restructuring plasmid pUC1019. These plasmids are useful as cloning vehicles in recombinant DNA work. For example, using DNA methodology, a desired gene, for example, the insulin gene, can be inserted into the plasmids and the resulting plasmids can then be transformed into a suitable host microbe which, upon culturing, produces the desired insulin.
