The Dot/Icm type IV secretion system (T4SS) is essential for the pathogenesis ofLegionellaspecies and translocates a multitude of effector proteins into host cells. The identification of host cell targets of these effectors is often critical to unravel their roles in controlling the host. Here we describe a method to characterize the protein complexes associated with effectors in infected host cells. To achieve this,Legionellaexpressing an effector of interest fused to a Bio-tag, a combination of hexahistidine tags and a specific recognition sequence for the biotin ligase BirA, are used to infect host cells expressing BirA, which leads to biotinylation of the translocated effector. Following chemical cross-linking, effector interactomes are isolated by tandem affinity purification employing metal affinity and NeutrAvidin resins and identified by western blotting or mass spectrometry.
