The information on requirements for T4SS substrate-channel docking

Certain T4SS substrates require secretion chaperones for translocation. These chaperones often possess physical properties (small size of 15 kDa, acidic pI, and amphipathic helices) resembling those of chaperones associated with the type III secretion systems, a family of macromolecular translocation systems ancestrally related to bacterial flagella.

#Accessory protein(GI)motif(s)Substrate(s)FunctionReference
1IcmS (chaperone) (212219340)NDAnkB, AnkH, AnkI, AnkJ, AnkMThe chaperone IcmS is essential for translocation into the host cytosol.(1) PubMed: 19411324
Tips:
1.Substrate(s): For the conjugation systems, the listed proteins are relaxases that bind a cognate T4CP and are delivered to recipient cells. For the effector translocator systems, the listed proteins are effectors that play a role in the infection processes of the bacterial pathogen.
2.motif(s):The motifs listed are required for substrate translocation. In some cases, the protein or its C-terminal fragment (CT) is sufficient to mediate translocation to target cells, as shown by fusion to a reporter protein such as Cre recombinase or adenylate cyclase. Amino acids (aa) at positions listed relative to the C-terminal fragment (subscript) are required for translocation, as shown by mutational analysis. ND, not determined. Parentheses indicate that the interaction between a protein substrate and a cognate T4CP has been experimentally shown.
3.Accessory protein: Accessory factors required for T4SS channel docking or translocation. The proposed function in mediating substrate-T4SS channel docking is shown in parentheses.PubMed:19946141
