Figure 9. (A) Partial sequence of the wild-type TonB2 from amino acid residues 168–206, (B) uptake kinetics and (C) Western blots.
Residues within loop 3 are in bold. The remaining residues of loop 3 after each deletion are depicted. (B) [55Fe]Anguibactin-uptake kinetics of mutants in loop 3. Results are means ± S.D. for at least three independent experiments. (C) Western Blots of loop-3 deletion derivatives.
