10652295-2	2000	The transition of rhodopsin from the inactive to the active state is associated with proton uptake at Glu(134) (1), and recent mutagenesis studies suggest that protonation of the homologous amino acid in the alpha(1B) adrenergic receptor (Asp(142)) may be involved in its mechanism of activation (2).
