Figure 7

Photocurrents generated in HEK293 cells by: (A) WT PsChR (solid line) and its K76F mutant (dashed line); (B) WT CaChR1 (dashed line) and its F139K mutant (solid line). Excitation wavelengths were (in nm): 440 for PsChR, 450 for PsChR_K76F, 520 for CaChR1, and 470 for CaChR1_F139K. In both panels the traces were normalized to their maximal value. Light excitation protocol is shown at the top. The numbers are time constants (τ) of current decay generated by its fitting with exponential functions.
