  • Title: Resonance Raman study of the dark-adapted form of the purple membrane protein.
    Author: Aton B, Doukas AG, Callender RH, Becher B, Ebrey TG.
    Journal: Biochim Biophys Acta; 1979 Feb 26; 576(2):424-8. PubMed ID: 427199.
    Abstract:
    The resonance Raman spectrum of the dark-adapted form of the purple membrane protein (bacteriorhodopsin) has been obtained and is compared to the light-adapted pigment and model chromophore spectra. As in the light-adapted form, the chromophore-protein linkage is found to be a protonated Schiff base. Electron delocalization appears to play the dominant role in color regulation. The dark-adapted spectrum indicates a conformation closer to 13-cis than the light-adapted spectrum.
