Chlamydia Outer Protein (Cop) B Interacts with T3S proteins. (a) GST-CopB1–255 or GST-CopB275–385 bound to glutathione-agarose beads (bait) pulled HisMBP-CdsF (prey) out of an E. coli lysate in the presence of a high salt wash buffer (500 mM NaCl). (b & c) Furthermore, GST-CopB fragments did not pull His-CopN or Cpn0803 out of an E. coli lysate in the presence of a high salt wash buffer
