Export of hybrid proteins FhuA'-'LacZ and FhuA'-'PhoA to the cell envelope of Escherichia coli K-12
1988
Journal of Bacteriology
The fhuA gene of Escherichia coli K-12 encodes an outer membrane protein that acts as the ferrichrome-iron(III) receptor. To determine the export signals and sorting information within FhuA, gene fusions of fhuA'-'lacZ and fhuA'-'phoA were constructed. Although a FhuA'-'LacZ hybrid protein was detected in the Triton X-100-insoluble fraction of the cell envelope, direct immunoelectron microscopic observation showed that this protein remained in the cytoplasm. FhuA'-'PhoA hybrid proteins were all
