Biphenyl-inducible promoters in a polychlorinated biphenyl-degrading bacterium, Rhodococcus sp. RHA1.


Five transcriptional promoters of biphenyl-degradation genes in Rhodococcus sp. RHA1 were characterized. We newly identified the etbA4 promoter region, which was located adjacent upstream from a ferredoxin reductase gene, etbA4 and a dihydrodiol dehydrogenase gene, bphB2. The etbA4 promoter activity was determined in RHA1 using a promoter probe vector with… (More)
