Molecular analysis of the Escherichia coli ferric enterobactin receptor FepA.

The Journal of biological chemistry - 25 Aug 1990

Armstrong S K, Francis C L, McIntosh M A

Abstract excerpt

In Escherichia coli, the outer membrane protein FepA is a receptor for the siderophore complex ferric enterobactin and for colicins B and D. To identify protein domains important for FepA activity, the effects of deletion and linker insertion mutations on receptor structure and function were examined. In-frame internal deletion mutations removing sequences encoding up to 304 amino acid residues resulted in...
