Photoexcitation of the O-intermediate in bacteriorhodopsin mutant L93A.

Biophysical journal - 1 Jun 2003

Abstract excerpt

During the extended lifetime of the O-state in bacteriorhodopsin (bR) mutant L93A, two substates have been distinguished. The first O-intermediate (OI) is in rapid equilibrium with N and apparently still has a 13-cis chromophore. OI undergoes a photoreaction with a small absorbance change, positive charge transport in the pumping direction, and proton release and uptake. None of these effects was detected after...
