title: Characterization by molecular cloning of insertion mutants in TOL catabolic functions.
abstract: A physical and genetic map of the Tol catabolic region of pWWO (TOL) was obtained by restriction endonuclease analysis of several DNA insertion mutants (xylA, xylA xylS, xylS, and xylR) of R plasmid--TOL derivatives. In two cases, the inserted DNA was shown from restriction, DNA hybridization, or heteroduplex analysis of cloned Hind III fragments to originate from within pWWO fragment Hind III-E. The effect of these DNA insertions on Tol catabolic activity and on structural alterations to the TOL plasmid is discussed.
