What is the real crystallographic structure of the L photointermediate of bacteriorhodopsin?
In the last few years, three laboratories have reported three entirely different crystallographic models for the L photointermediate of bacteriorhodopsin. All are from X-ray diffraction of illuminated crystals that contain L in photostationary states created at similar cryogenic temperatures. This article compares the models and their implications, the crystallographic statistics and the methods used to derive them, as well as their agreement with non-crystallographic information.
