Abstract
The genes for the degradation of 3-chlorobenzoic acid ( 3Cba ) are present in a 110-kb plasmid pAC27 . A circular map is established using the restriction endonucleases EcoRI, HindIII and Bg/II. The map is derived from the results obtained by partial restriction digestion, complete single and double restriction digestion and finally confirmed with hybridization of the digested fragments using different purified fragments as probes. The 3Cba degradative genes are found to be clustered in one region of the map (EcoRI fragment A) as judged by molecular cloning with a broad host range vector pLAFRI . A portion of the 3Cba degradative gene cluster appears to undergo ready recombination with the chromosome, even in a recA host, suggesting the probable transposable nature of such gene cluster.
