Regulatory regions of smeDEF in Stenotrophomonas maltophilia strains expressing different amounts of the multidrug efflux pump SmeDEF.

Patricia Sanchez1, Ana Alonso, Jose L Martinez.   

Abstract

The smeT-smeDEF region and the smeT gene, which encodes the smeDEF repressor, are highly polymorphic. Few changes in smeT might be associated with smeDEF overexpression. The results obtained with cellular extracts suggest that mutant SmeT proteins cannot bind to the operator and that other transcription factors besides SmeT are involved in the regulation of smeDEF expression.
