Abstract
NahR, a LysR-type transcriptional regulator, is required for expression of naphthalene catabolic operons. However, detailed mechanisms of transcriptional activation by NahR are poorly understood. Many transcriptional activators make direct contact with RNA polymerase (RNAP) to initiate transcription. We investigated the hypothesis that direct contact between NahR and the α subunit of RNAP (αRNAP) may be involved in expression of the naphthalene catabolic operons in Pseudomonas putida NCIB 9816-4. Interactions between the NahR and αRNAP in P. putida NCIB 9816-4 were analyzed using the yeast two-hybrid system. The results obtained indicate that protein-protein interactions occur between αRNAP and the NahR. Gene activation by NahR is consistent with the general transcriptional mechanism of class I transcription factors, which function by contacting αRNAP.
