== Publication Abstract from PubMed ==
 +
The atomic structure of the trans isomer of bacteriorhodopsin was determined previously by using a 3D crystal belonging to the space group P622. Here, a structure is reported for another isomer with the 13-cis, 15-syn retinal in a dark-adapted crystal. Structural comparison of the two isomers indicates that retinal isomerization around the C13[double bond]C14 and the C15[double bond]N bonds is accompanied by noticeable displacements of a few residues in the vicinity of the retinal Schiff base and small re-arrangement of the hydrogen-bonding network in the proton release channel. On the other hand, aromatic residues surrounding the retinal polyene chain were found to scarcely move during the dark/light adaptation. This result suggests that variation in the structural rigidity within the retinal-binding pocket is one of the important factors ensuring the stereospecific isomerization of retinal.
