RdmB Activates the Quorum Quenching Activity of Pseudomonas nitroreducens HS-18 by Direct Regulating Two Sets of DSF Signal Degradation Enzymes.
Findings demonstrated that RdmB and RdmA constitute a potent pair of regulators to modulate DSF metabolism in response to environmental changes and physiological need, which would allow QQ agent HS-18 to activate DSF degradation enzymes when necessary, thus keeping its fitness and competitive edges.
