The coding sequence of the coding sequence of the arcA gene in SE8743 were identical , suggesting that the difference in resistance to RNI/ROI maybe due to the activity of genes regulated by ArcA .
The coding sequence of the arcA gene in SE2472 were identical , suggesting that the difference in resistance to RNI/ROI maybe due to the activity of genes regulated by ArcA .
To obtain a global view of ArcA-controlled biological processes , we classified proteins with altered expression levels in S. Typhimurium arcA cells into Clusters of Orthologous Groups ( COGs ) ( Table I ) .
