Photoisomerization mechanism of rhodopsin and 9-cis-rhodopsin revealed by x-ray crystallography.

ABSTRACT: The primary photochemical process of the visual function has been investigated using the three crystallographic models, 11-cis-rhodopsin, all-trans-bathorhodopsin, and the artificial isomeric 9-cis-rhodopsin. Detailed examination of the atomic displacements and dihedral angle changes of the retinal chromophore involved in the interconversion among these isomers suggests the mechanism of isomerization efficiency.
