The plug domain of FepA, a TonB-dependent transport protein from Escherichia coli, binds its siderophore in the absence of the transmembrane barrel domain

FepA, an outer membrane iron siderophore transporter from Escherichia coli, is composed of a 22-stranded membrane-spanning β barrel with a globular N-terminal “plug” domain of 148 residues that folds up inside the barrel and completely occludes the barrel's interior (1). We have overexpressed and pu...
