Figure 6. Relative permeation of neutral and charged solutes through Omp38.

Figure 6

Purified native BpsOmp38 was reconstituted into liposome vesicles. The permeabilities of various sugars and antibiotics through BpsOmp38 were determined as described in the text, and the permeability of the channel was assumed to be proportional to the swelling rate. The size-dependent permeation rates for sugars (□) and antibiotics (■) were plotted on a logarithmic scale, and the values are normalized to the permeation rate of L-arabinose. The broken and solid lines are a regression fit to all the data for sugars and antibiotics respectively.
