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 regeneration from bacterioopsin proceeds to a normal extent in the presence of a single aspartate or glutamate residue at position...
