The bacteriorhodopsin gene. [PDF]

Proceedings of the National Academy of Sciences, 1981
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 ...

Meniscus‐Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra‐Stiff 15 MHz MEMS AFM Probes

Journal of Molecular Recognition, Volume 39, Issue 3, May 2026.
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.

Photochemical characterization of a novel fungal rhodopsin from Phaeosphaeria nodorum [PDF]

, 2011
Eukaryotic microbial rhodopsins are widespread bacteriorhodopsin-like proteins found in many lower eukaryotic groups including fungi. Many fungi contain multiple rhodopsins, some significantly diverged from the original bacteriorhodopsin template ...

Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

Acta Crystallographica Section D, Volume 82, Issue 5, Page 471-483, May 2026.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...
