Upon incubation with all-trans retinal, Air-AAR1-like[DELTA]58 produced a dark pigment that clearly reacted to amber light (~592 nm) (Fig.
The sinusoidal shape of the differential spectra of Air-CCAPR1-Like[DELTA]105 incubated with either 11-cis or all-trans retinal clearly indicates a change after exposure to light (Fig.
The mutants were tested with the chromophore that gave the best result for each of the two GCPRs: 11-cis retinal for Air-CCAPR1-Like[DELTA]105 and all-trans retinal for Air-AAR1-Like[DELTA]58.
