PPR suppresses the secretion of T3SS effector proteins. (A) The β-lactamase reporting system was used to detect the effect of PPR on the translocation of the ST T3SS (scale bar, 100 μm). (B) TCA precipitation assay combined with Coomassie Brilliant Blue (CBB) staining to detect the effects of PPR on T3SS effector protein secretion. (C) Detection of the impact of PPR on the expression of the effector protein SipA via WB.
