Figure 6. Single-channel recordings (A, D) and the corresponding current histograms (B, E) of gramicidin A (picogram/ml, A, B, and C) and [Glu1]gA (2 nanogram/ml, D, E, and F) at a voltage of 100 mV applied to the DPhPC/decane membrane.

Figure 6

The solution was 100 mM HCl. (C, F) Open state duration histograms fitted by a single exponential with a time constant of 116 ms (C) and 16 ms (F). The records were filtered at 100 Hz (A, B, and C) or 1000 Hz (D, E, and F).
