| Escherichia coli |
Leucine is toxic for cell growth in ptsN mutants. |
EIIANtr |
Elevated K⁺ concentration inhibits AHAS I activity and synthesis. Therefore, leucine inhibits remaining AHAS III |
| EIIANtr inhibits K⁺ influx at high K⁺ concentrations |
EIIANtr |
EIIANtr binds low affinity K⁺ transporter TrkA |
| EIIANtr stimulates K⁺ influx at low K⁺ concentrations |
EIIANtr |
EIIANtr binds to and stimulates KdpD kinase, which mediates high affinity K⁺ transporter KdpFABC synthesis |
| dephospho-EIIANtr inhibits K⁺ limitation whereas external K⁺ signal stimulates it |
EIIANtr |
Dephosphorylated EIIANtr inhibits YcgO K⁺ efflux activity |
