Module swaps between related translocator proteins pIV(f1), pIV(IKe) and PulD: identification of a specificity domain.

Abstract excerpt

In Gram-negative bacteria, type II and type III secretion and filamentous phage assembly systems use related outer membrane proteins for substrate-specific transport across the outer membrane. We show here that the specificity domain of the phage f1 outer membrane protein pIV is contained within the 149 N-terminal amino acid residues. When the pIV(f1) specificity domain is fused to the translocator domain of the...
