The retinylidene Schiff base counterion in bacteriorhodopsin.

The Journal of biological chemistry - 5 Oct 1991

Marti T, Rösselet S J, Otto H, Heyn M P, Khorana H G

Abstract excerpt

Previous studies of bacteriorhodopsin have indicated interactions between Asp-85, Asp-212, Arg-82, and the retinylidene Schiff base. The counterion environment of the Schiff base has now been further investigated by using single and double mutants of the above amino acids. Chromophore regeneratio...
