WebIn the purple membrane (PM) of Halobacterium salinarum, bacteriorhodopsin (bR) monomers associate to form a trimeric structure, and the trimers arrange in a hexagonal lattice (Henderson et al., 1990).The 2D crystals of bR and any crystals in general are in dynamic equilibrium with the constituents at the interface between crystal and liquid.
Characterization and composition of the purple and red membrane …
WebAbstract. Halobacterium halobium cells grown under semi-anaerobic conditions convert part of their cell membrane into “purple membrane” which contains a rhodopsin-like protein, bacteriorhodopsin. Under anaerobic conditions in the dark the ATP content of such cells decreases sharply. Either light or oxygen restores the ATP content to the original level. WebThe light-driven proton pump bacteriorhodopsin (BR) from the extreme halophilic archaeon Halobacterium salinarum is a retinal-binding protein, which forms highly ordered and thermally stable 2D crystals in native membranes (termed purple membranes). BR and purple membranes (PMs) have been and are still being intensively studied by numerous … ptsd in healthcare workers
