Abstract |
The restriction clevage map of multi-copy recombinant plasmid, pJY712(8.1kb), carrying the thiostrepton resistance gene(tsr) was determined. pJY712 had a broad host range in Streptomyces and contained single BglII site for cloning purpose. The plasmid showed the phenomenon of lethal zygosis (Ltz^+). Transformation frequency of pJY712 was 5.0×10^4 transformants per ug plasmid DNA (TFU) in S. lividans. Plasmid pJY713 was constructed by inserting the tyrosinase gene(mel) into the BclI site of pJY712. Recombinant plasmid pJY714 carrying the mel gene was constructed by in vitro deletion of a segment (1.9kb BglII-BclI fragment) from pJY713. |
