| This reaction should take place in darkroom conditions to protect the aryl azide from photolysis. |
| Upon replacement of chloride ion with azide, the fast electric signal changes its sign from positive to negative, and becomes similar to that detected in bacteriorhodopsin. |
| This indicates that the bound azide is required to detect the 410-nm signal and suggests that azide plays the role of the proton acceptor. |
| Animals that reached the odorant or control were trapped by a spot of sodium azide. |
| Similar dose-dependent inhibition was also observed in the time-course experiments using vanadate and azide. |
| Another anion, azide, is used in the study of bacteriorhodopsin mutants as a substitute for proton donor or acceptor when they are altered in the protein. |
