Au activates the expression of cpxP , the archetypical CpxR/CpxA-regulated gene To test if in the presence of Au , other members of the Cpx regulon are induced , we measured the expression of cpxP , coding for a key component of the CpxR/CpxA signal transduction pathway known to acts as a CpxA modulator ( Hunke et al. , 2012 ; Raivio , 2014 ; Grabowicz and Silhavy , 2016 ) .
