Activating Compound | Comment | Organism | Structure |
---|---|---|---|
additional information | activation of RK by metarhodopsin II and III, their phosphorylated derivatives, all the derivatives of opsin, which contain the Schiff base linkage with the all-trans-retinylidene moiety, but not opsin | Ovis sp. | |
rhodopsin | RK normally exists in an inactive resting state and is only activated following interaction with photoactivated rhodopsin | Ovis sp. | |
rhodopsin | metarhodopsin II and III, or their phosphorylated derivatives activate | Ovis sp. |
