Abstract

Chlorocatechol 1,2-dioxygenase (CC12O) and 1,2-dichlorophenol hydroxylase (DCPH) encoding genes tfdC and tfdB are located on a 4.2-kb DNA fragment cloned from the 2,4-dichlorophenoxyacetic acid (2,4D) degrading plasmid pEST4011. The nucleotide sequences of tfdC and tfdB were determined. The DCPH is coded by a 1758-bp gene and CC12O is coded by a 762-bp gene. The deduced M(r) of these proteins are 64.09 kDa and 28.2 kDa, respectively. Expression analysis of tfdB and tfdC in Escherichia coli suggested that these genes form one operon, tfdCB.
