Ybt-dependent Zn2+ acquisition does not require the OM Ybt receptor Psn or any other TonB-dependent OM receptor. Cells were grown at 37°C in cPMH2 supplemented with 0.6 μM ZnCl2 and 1.0 μM FeCl3 or 1.0 μM FeCl3 alone. Strains: KIM6-2045.1 (Psn- [Δpsn] Znu+); KIM6-2077+ (Ybt+ Znu- [ΔznuBC]); KIM6-2077.7 (HMWP2- [irp2∷kan] Znu- [ΔznuBC]); KIM6-2077.12+ (Znu- [ΔznuBC] TonB-[tonB∷kan] HasB- [ΔhasB]); Psn- Znu- (KIM6-2077.9 [psn∷kan ΔznuBC], ▼ and KIM6-2077.14 [Δpsn ΔznuBC];◆). Psn is the OM receptor for Ybt and HasB is a second TonB-like protein in Y. pestis (Perry and Fetherston, 2011; Perry et al., 2003b). Growth curves shown are from one experiment that is representative of two or more independent experiments.
