A cleavage map of the TOL plasmid pWWO has been determined for the restriction endonucleases HindIII and XhoI. A number of techniques were employed including (i) digestion of purified cleavage products with a second enzyme; (ii) hybridisation of purified XhoI fragments to Southern blots of HindIII d

Some of a set of independently arising Tol- (non toluate-utilising) derivatives of Pseudomonas putida mt-2 have lost the unique plasmid present in the parent strain. In others this plasmid has suffered a deletion of a specific region of about 27 Md.
Cleavage sites on the pWWO-8 plasmid were determined for the restriction endonucleases HindIII and XhoI. Terminal labelling using DNA polymerase I was particularly useful both for the characterisation of the smaller cleavage products and for confirmation of the order of fragments in the intact plasm
