Figure 2
(a) Absorption spectra of retinal-bound M1 at pH 4 monitored over time. Maximum PSB is detected after 30 min (blue line). The PSB is not stable and thermally converts to SB over time (red line, two days). (b) Incubation of M1 with retinal for 48 h (blue line). UV light irradiation converts the Schiff base to PSB (black line). Note the residual PSB absorption even after 48 h. |
