Organization and Transcriptional Characterization of Catechol Degradation Genes Involved in Carbazole Degradation by<i>Pseudomonas resinovorans</i>Strain CA10

Abstract

Pseudomonas resinovorans strain CA10 assimilates catechol, which is an intermediate of carbazole degradation, by ortho cleavage pathway enzymes encoded by the catR, catBCA operon. Cat proteins of strain CA10 were very similar to those of P. putida, although the relatedness in non-coding regions was not high. It was found that catBCA genes were induced in carbazole-grown cells as a single transcriptional unit.
