Table 1 Characteristics of three phases of Δψ generation by NaR reconstituted into liposomes.
Phase | τ at [Na+] = 200 mM in H2O | τ at [Na+] = 200 mM in D2O | Contribution to total Δψ generation | Dependence on Na+ concentration |
|---|---|---|---|---|
I | 25 μs | 35 μs | 15% | No |
II | 0.9 ms | 0.9 ms | 15% | ? |
III | 4.5 ms | 9 ms | 70% | Yes |
