Abstrakt: Fragmentation of wall-eyed pollock and bovine rhodopsins by papain in the photoreceptor membrane was studied by sodium dodecyl sulfate electrophoresis. A scheme of step-wise rhodopsin proteolysis is presented. The molecular weights and localization of the carbohydrate and chromophore components of the fragments formed were determined. The data obtained suggest that the photoreceptor membranes of both rhodopsins contain three sites accessible to water environment and are indicative of topographical similarity of the rhodopsins.
