Absorption spectra of single outer segments of the frog Rana temporaria photoreceptors were registered. Effects of nitrate and chloride ions on spectral properties of cone and rod pigments were compared. These pigments proved to differ in structure of the native photoreceptor membrane and, therefore, in effect of hydrophile environment on the chromophore centrum. Substitution of chloride by nitrate ions led to the hypochromic shift of the cone absorption spectrum (20-25 nm) but does not affect the spectrum on case of rod pigment. The ionochromic behaviour of cone pigments resembles that of the light-sensitive halobacterium protein halorhodopsin, in native membrane. We suppose that the effect of anions on the chromophore centrum may be the cause of bathochromic shifts of absorption spectra of longwave-length retinal-containing pigments.
