| Popis: | Phosphorylation of rhodopsin has been measured in isolated retinas incubated with 32P-phosphate under physiological conditions. The half-time of the light-induced phosphorylation was found to be approximately 2 min with frog retinas at 21 degrees C, and in the order of 1--2 min with cattle retinas at 36 degrees C. It is suggested by this slow rate that the phosphorylation reaction is not directly involved in the chain of events which lead from absorption of a photon to excitation of the photoreceptor cells but may perhaps have a regulatory function in controlling light/dark adaptation. |
