Activating Compound | Comment | Organism | Structure |
---|---|---|---|
gamma-subunit of cGMP phosphodiesterase | accelerate GTP hydrolysis by transducin | Bos taurus | |
gamma-subunit of cGMP phosphodiesterase | the GTPase activating epitope is located within the C-terminal third of phosphodiesterase | Bos taurus | |
rhodopsin | transducin is activated by photoexcited rhodopsin which catalyzes the exchange of transducin-bound GDP for GTP and then stays active until bound GTP is hydrolyzed by the intrinsic GTPase activity | Bos taurus |
