Abstract excerpt
Photoinduced changes in absorption of the deprotonated M-form in the mutant bacteriorhodopsin without primary proton acceptor Asp-85 were studied and additional evidence in support of the complete transmembrane proton transfer in photocycle was obtained. Measurements of the absorption spectrum were carried out at various pH, temperature, and humidity. The direction of proton transfer was the same as in the normal...
