Binding of calcium ions to bacteriorhodopsin.

Biophysical journal - 1 Jun 1999

Váró G, Brown L S, Needleman R, Lanyi J K

Abstract excerpt

Adding Ca2+ or other cations to deionized bacteriorhodopsin causes a blue to purple color shift, a result of deprotonation of Asp85. It has been proposed by different groups that the protonation state of Asp85 responds to the binding of Ca2+ either 1) directly at a specific site in the protein or 2) indirectly through the rise of the surface pH. We tested the idea of specific binding of Ca2+ and found that the...
