Rod transducin (Tr), a heterotrimeric GTP-binding protein composed of alpha, beta, and gamma subunits, couples photolysis of rhodopsin to the activation of cyclic GMP phosphodiesterase in the vertebrate visual signal transduction cascade. To determine if T alpha r is covalently modified, we analyzed tryptic fragments of bovine retinal T alpha r using electrospray mass spectrometry, liquid chromatography/mass spectrometry, tandem mass spectrometry, and gas chromatography. A novel heterogeneous… CONTINUE READING
