SecA-independent translocation of the periplasmic N-terminal tail of an Escherichia coli inner membrane protein (original) (raw)

1995, Journal of Biological Chemistry

We have shown previously that the 100-residue-long periplasmic N-terminal tail of the Escherichia coli inner membrane protein ProW can be translocated across the inner membrane in a sec-independent manner and that its translocation is blocked by the introduction of three positively charged residues near its C-terminal end (Whitley, P., Zander, T., Ehrmann, M., Haardt, M., Bremer, E., and von Heijne, G.(1994) EMBO J. 13, 4653-4661). We have now further analyzed the requirements for translocation of the N-terminal tail and ...
