Crystal structure of Halobacterium salinarum halorhodopsin with a partially depopulated primary chloride-binding site

In conclusion, the conformation of the chloride-free protein may not be compatible with this crystal form of HsHR despite a packing arrangement that hardly restrains helices E and F that presumably move during ion transport.
