Abstract:
A 2,4 -dichlorophenol degrading Pseudomonas strain GI241-1 was isolated from a soil sample. The dienelactone hydrolase gene, designated as dcpD which encodes dienelactone hydrolase involved in transforming cis-2-chloro-dienelactone into 2-chloromaleylacetic acid, was cloned from this bacterium strain. The gene cloning strategy was to construct genomic library after location of its neighbouring gene by Southem blot and to screen the aim transformant by dot blotting. Sequencing results showed that length of dcpD is 702bp. The sequence of dcpD and the deduced amino acid are different from the relative sequences registered in the GenBank.
