Figure Lengend Snippet: Physical and functional map of pHYK2000. (A) Restriction map of the 14.3-kb BamHI-HindIII DNA fragment from Burkholderia sp. strain JS150 cloned into vector pRO1727 as pHYK2000. The XhoI-HindIII fragment used as a probe is indicated. (B) Southern hybridization results for DNA digested with XhoI and HindIII. Lanes: C, control (cloned) DNA; Ch, chromosomal DNA; P, plasmid DNA. (C) Construction of deletion mutants of pHYK2000 and assays for substrates oxidized by each construct. For functional mapping of pHYK2000, HindIII, NotI, XhoI, BamHI-XhoI, and HindIII-XhoI deletions were constructed, and the constructs were used to assay for oxidation (+, weak; ++, intermediate; +++, strong) of toluene (Tol), benzene (Ben), and chlorobenzene (Chlb).
