1950 G. Wald et al. in Science 17 Feb. 180/1 On exposing the solution to light at these low temperatures, the maximum shifts about 5 mμ toward the blue, rising about 5% in height in cattle rhodopsin, falling about this amount in frog rhodopsin, still with little change in shape. This is the light reaction. We shall call its product lumirhodopsin.
1975 Nature 3 Jan. 56/2 Lozier and Stoeckenius have observed [in Halobacterium halobium] four spectrally distinct intermediates analogous to the rhodopsin, prelumirhodopsin, lumirhodopsin and metarhodopsin of invertebrates.
