Abstract	Retinal analogues with altered conjugated double bond systems or altered stereochemistry were incorporated into the phototaxis receptor sensory rhodopsin (SR) and the light-driven proton pump bacteriorhodopsin (BR) from Halobacterium halobium. Wavelength shifts in absorption ("opsin shifts") due to analogue interaction with the protein microenvironment demonstrate that the same overall electrostatic and steric properties of the retinal binding-site structures exist in both proteins despite their different functions. pi-Electron calculations from the opsin shifts lead to a new description of protein charge distribution that applies to the binding sites of both SR and BR. The new data extends the previously proposed external point charge model for BR to include an ion-pair protein/chromophore interaction near the beta-ionone moiety. The new data modifies the previously proposed external point-charge model, the derivation of which involved an experimentally erroneous opsin shift for one of the BR analogues.
