Figure 1. The structure of rhodopsin.

Figure 1

The tertiary structure of bovine rhodopsin from the intradiscal N-terminus (dark blue) to the cytoplasmic C-terminus (red) containing 7 transmembrane motifs (α-helix I-VII) and cytosplamic helix VIII shown in a 3D model. 11-cis retinal (black), T4, P23, E113, R135, K296 and the disulphide bond site C110-C187 are highlighted. The 3D image was made using PyMol (PDB 1U19).
