FIG 6.

Coimmunoprecipitation analysis suggests the formation of LbcA-independent complexes between CtpA substrates and nonsubstrates. Each panel shows immunoblot analysis of input lysates and immunoprecipitates (Anti-FLAG IP). Strain genotypes are shown above each lane. Polyclonal antisera used for detection are shown at the left. (a) Baits were RlpA-FLAG or the RlpA negative control. (b) Baits were LbcA-FLAG or the LbcA negative control. (c) Baits were PA1198-FLAG or the PA1198 negative control. (d) Baits were RlpA-FLAG or the RlpA negative control. (e) Baits were MltD-FLAG or the MltD negative control. Immunoblots are single representatives of results from several independent replicate experiments.
