摘要

Nocardioides sp. DF412 degrades dibenzofuran (DF) to salicylate through the sequential actions of DF dioxygenase (dfdA), extradiol dioxygenase (dfdB), and hydrolase (dfdC). The involvement of a TetR-type regulator gene dfdS in the dfdB and dfdS gene expression was investigated. A reporter assay using a luciferase gene indicated repression of dfdB and dfdS promoter activities in the presence of the dfdS gene product, DfdS. Gel shift analysis ...
