Abstract
LIGHT induces changes in the visual pigment rhodopsin and its retinaldehyde prosthetic group1 but the specific chemical events which lead to photoreceptor excitation remain obscure. We describe here a phosphorylation reaction initiated by rhodopsin bleaching which may be part of the mechanism linking photon absorption to changes in membrane resistance.
