Table 1. Comparison of Transport Properties in Large and Giant Proteoliposomes.
diameter (μm) | surface (μm2) | volume (μm3) | TmrAB/vesicle | transport rate (1/min) | |
---|---|---|---|---|---|
LUVs | ∼0.1a | 0.06a | 0.5 × 10–3a | 25a | |
GUVs | 10.9b | 820b | 920b | ∼0.5 × 106 | 0.31b |
GUVs | 19.0c | 2600c | 5200c | ∼1.5 × 106c | 0.50c |
Derived from ref. (11) for proteoliposomes incubated in 10 μM C4F at 68 °C.
Parameters are means obtained from 19 individual single GUVs for the addition of 1 μM C4F.
Parameters are means obtained from 17 individual single GUVs for 3 μM C4F. Rate constants of GUVs are given as medians.
