Since PhoP is a transcriptional activator of the iraP -LRB- yaiB -RRB- gene , we therefore regulate spvRABCD .
Since PhoP is a transcriptional activator of the iraP -LRB- yaiB -RRB- gene , we postulate that the RstA/RstB systems might coregulate iraP to control RpoS .
Since PhoP is a transcriptional activator of the iraP -LRB- yaiB -RRB- gene , we postulate that the PhoP/PhoQ systems might coregulate iraP to control RpoS .
