Interaction Information:

Comment The authors showed that 10 T4SS substrate mutants, among 20 mutants analysed, exhibited defects in intracellular growth and CCV formation in HeLa and J774A.1 cells, but displayed normal growth in bacteriological medium. Six substrate mutants (Cbu0041, Cbu0388, Cbu0425, Cbu0937, Cbu2052, and Cbu2059) were unable to replicate in J774A.1 cells or HeLa cells. Due to their role in intracellular replication and CCV formation, Cbu0041, Cbu0425, Cbu0937, Cbu2052, and Cbu2059 were renamed to cirA, cirB, cirC, cirD, and cirE (Coxiella effector for intracellular replication), respectively.
