Lipid composition of integral purple membrane by 1H and 31P NMR
In the purple membrane (PM) of halobacteria, lipids stabilize the trimeric arrangement of bacteriorhodopsin (BR) molecules and mediate the packing of the trimers in a regular crystalline arrangement.

The bacteriorhodopsin gene. [PDF]
The bacteriorhodopsin gene has been identified in a 5.3-kilobase restriction endonuclease fragment isolated from Halobacterium halobium DNA, using a cloned cDNA fragment as the probe. Of the 1229 nucleotides whose sequence was determined in the genomic fragment, 786 correspond to the structural gene of bacteriorhodopsin, 360 are upstream from the ...

Structural studies of bacteriorhodopsin in BC era
It marked half a century since the discovery of bacteriorhodopsin two years ago. On this occasion, I have revisited historically important diffraction studies of this membrane protein, based on my recollections. X-ray diffraction and electron diffraction,

Large scale preparation of homogeneous bacteriorhodopsin [PDF]
Homogeneous bacteriorhodopsin was obtained preparatively (100 mg batches) from purple membrane of Halobacterium halobium cells. The homogeneity of the protein was considerably affected by variations in the growth conditions of the bacteria.

Ionic Polymer Microactuator Activated by Photoresponsive Organic Proton Pumps
An ionic polymer microactuator driven by an organic photoelectric proton pump transducer is described in this paper. The light responsive transducer is fabricated by using molecular self-assembly to immobilize oriented bacteriorhodopsin purple membrane ...

Absorption characteristics of bacteriorhodopsin molecules
The bacteriorhodopsin molecule absorbs light and undergoes a series of structural transformation following a well-defined photocycle. The complex photocycle is transformed to an equivalent level diagram by considering the lifetime of the intermediate ...

ABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.

The operation of bacteriorhodopsin (BR) from the archaeon Halobacterium salinarum is based on the photochromic reaction of isomerization of the chromophore group (the retinal protonated Schiff base, RPSB) from the all-trans to the 13-cis form.
