Properties of the FhuA channel in the Escherichia coli outer membrane after deletion of FhuA portions within and outside the predicted gating loop.

Escherichia coli transports Fe3+ as a ferrichrome complex through the outer membrane in an energy-dependent process mediated by the FhuA protein. A FhuA deletion derivative lacking residues 322 to 355 (FhuA delta322-355) forms a permanently open channel through which ferrichrome diffused. This findi...
