Abstract excerpt
In the photocycle of bacteriorhodopsin (BR), the first proton movement, from the Schiff base to Asp85, occurs after the formation of the L intermediate. In L, the C [double bond] N bond of the Schiff base is strained, and the nitrogen interacts strongly with its counterion. The present study seeks to detect the interaction of internal water molecules with the Schiff base in L using difference FTIR spectroscopy at...
