Figure 7. Mean currents recorded for the wild-type and mutation in the presence of various Mg-nucleotides.

1. Mean wild-type (white bar, n = 17) and hetT294M (black bar, n = 12) currents recorded in the presence of 0.1 mM MgATP, 0.1 mM MgADP or 0.1 mM MgATP plus 0.1 mM MgADP.
2. Mean wild-type (white bar, n = 6) and hetT294M (black bar, n = 7) currents recorded in the presence of 0.1 mM MgGTP, 0.1 mM MgGDP or 0.1 mM MgGTP plus 0.1 mM MgGDP. Currents (G) are expressed relative to the mean of the currents recorded in control solution (G_c) before and after the application of nucleotide.
