Plasmid puc6, this culture containing of streptomyces espinosus and method for the isolation of plasmid puc6 from streptomyces espinosus

摘要

A novel chemical compound, essentially pure plasmid pUC6, which is obtainable from a biologically pure culture of the microorganism Streptomyces espinosus biotype 23724a, NRRL 11439. The pUC6 plasmid is useful as a cloning vehicle in recombinant DNA work. For example, using DNA methodology, a desired gene, for example, the insulin gene, can be inserted into pUC6 and the resulting plasmid can then be transformed into a suitable host microbe which, upon culturing, produces the desired insulin.
