Abstract

Efflux pumps were found to be the most efficient mechanism of hydrocarbon tolerance in several bacterial strains resistant to solvents and other toxic chemicals. This involves an energy-dependent process that ensures the active removal of toxic compounds from the bacterial cytoplasm to the external medium. In order to achieve the maximal response of the process, regulatory networks of RND efflux pumps (resistance-nodulation-cell division family of bacterial transporters) are complex and modulated by the simultaneous coordination of many transcription factors in response to perturbations and cellular states. Several studies in the literature report the identification and molecular characterization of regulatory genes of RND efflux pumps, acting as global or specific regulators, activating or repressing transcription. In this sense, the main objective of this chapter is to provide a general view of the regulatory networks used by bacteria to modulate the response to toxic hydrocarbons mediated by efflux pumps. We also explore conceptual properties that remain conserved in different regulatory systems and outline common principles of RND regulation in gram-negative bacteria.
