WebHalobacterium halobium is a red bacterium found in lakes that have a high salt content. It can form ATP in the light in a quite unusual way. The membrane of the bacterium … WebOct 3, 2000 · The cell envelope of Halobacterium NRC-1 consists of a single lipid bilayer membrane surrounded by an S-layer assembled from the cell-surface glycoprotein . Although the cytoplasm is in osmotic equilibrium with the hypersaline environment, the cell maintains a high (≈4 M) intracellular K + concentration that is equivalent to the …
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. WebWHEN Halobacterium halobium is grown at low oxygen concentrations in the light, it synthesises patches of membrane containing a purple pigment. If exposed to low salt concentrations, the cell ...

BR and purple membranes (PMs) have been and are still being intensively studied by numerous …
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.
