Temperature-sensitive mutants of the Streptomyces plasmid pIJ702.
DNA from the Streptomyces plasmid pIJ702 was mutagenized in vitro using hydroxylamine and transformed into Streptomyces lividans. One plasmid with temperature-sensitive replication (pMT660) and one plasmid with a temperature-sensitive tyrosinase (pMT661) were isolated. The plasmid pMT661 contains a novel PstI restriction endonuclease site within the tyrosinase gene.
