| Abstract: | Staphylococcal plasmids pTP4 (2.7 megadaltons encoding resistance to chloramphenicol) and pTP5 (2.6 megadaltons encoding resistance to tetracycline), which replicate and express resistance in B. subtilis, were found to cut by HindIII endonuclease respectively at a single site and three sites. A chimeric plasmid pTA1245 (4.1 megadaltons) was constructed from pTP4 and pTP5 by HindIII digestion and ligation with E. coli DNA ligase. pTA1245 expresses resistances to chloramphenicol and tetracycline in B. subtilis, and pTA1245 is amplified in the presence of tetracycline. A physical map of pTA1245 was constructed. |
