DNA extracted from a sytA::Tn10::ori-spc transformant was cut with restriction enzymes that do not cut into the Tn10::ori-spc sequence; plasmids containing the sytA::Tn10 insertion were cloned by self-ligation, followed by transformation of E. coli. To obtain the wild-type sytA region, one of these plasmids was ligated with an E. coli-B. subtilis shuttle vector conferring erythromycin resistance, and the hybrid was used to transform the wild-type B. subtilis strain. Erythromycin-resistant transformants, detected as spectinomycin sensitive, resulted from conversion of the insertion mutation by the resident wild-type locus.
