Abstract
Bacteriorhodopsin from Halobacterium halobium has been solubilized in the nonionic detergent Triton X-100. The circular dichroic spectrum and hydrodynamic properties indicate that the structure of this protein in the detergent is not significantly altered from that of the native membrane-bound form. Bacteriorhodopsin is monomeric under the conditions of solubilization with a molecular weight of 24,250+/-2,000 and binds approximately one micelle of Triton X-100.
