Moreover , the pagC gene is positively regulated by SlyA .
Finally , relative pagC gene expression showed a significant decrease of ~ 0.9-fold in DSlyA in this condition , suggesting that SlyA positively regulates pagC expression .
Within the virulence coincident genes , we determined that pagC is positively regulated by SlyA .
SlyA interaction with the promoter region of pagC occurred at a SlyA concentration of Fig. 4G , suggesting that SlyA positively regulates pagC expression .
SlyA interaction with the promoter region of pagC occurred at a SlyA concentration of 9.09 nM , suggesting that SlyA positively regulates pagC expression .
