This Type IVb secretion system (T4bSS) is responsible for the delivery of protein effectors to the host cell cytoplasm. The middle region of IcmR (this entry) binds to the N-terminal domain of IcmQ, which is essential for IcmQ (Pfam:PF09475) to function correctly. The interacting domains form helical hairpins within a four-helix bundle that is stabilized by hydrophobic packing [1,2].
