The ability of the PPR to suppress T3SS secretion is unrelated to HilA. (A) The simplified regulatory network for the T3SS. (B) Western blotting was used to assess the impact of HilA overexpression on the production of T3SS effector proteins. (C) A CBB assay was used to investigate the effect of HilA overexpression on the secretion of T3SS effector proteins. (D) Western blotting was used to examine the effect of overexpression of HilA on the secretion of the T3SS effector protein SipA.
