Sequence Changes in the Ton Box Region of BtuB Affect Its Transport Activities and Interaction with TonB Protein

Uptake of cobalamins by the transporter protein BtuB in the outer membrane of Escherichia coli requires the proton motive force and the transperiplasmic protein TonB. The Ton box sequence near the amino terminus of BtuB is conserved among all TonB-dependent transporters and is the only known site of...
