Deep Mutational Scanning for the Study and Engineering of Protein Assemblies

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review explores how deep mutational scanning (DMS) can be used to improve understanding and accelerate engineering of protein assemblies, from natural fibers to engineered nanocages. We discuss various types of protein assemblies and their characterization, provide an introduction to the DMS technique, and then highlight examples in which DMS has ...

Photoactive bacteriorhodopsin variants [PDF]

, 1997
Bacteriorhodopsin variants were generated by UV mutagenesis. The protein variants thus engineered were characterized for their UV-visible absorption, light induced proton release activity and photocycle kinetics (BR→M)

Osmotic shock induces the presence of glycocardiolipin in the purple membrane of Halobacterium salinarum

Journal of Lipid Research, 2003
In the purple membrane (PM) of Halobacterium salinarum is present a phospholipid dimer consisting of sulfo-triglycosyl-diether (S-TGD-1) esterified to the phosphate group of phosphatidic acid (PA), i.e., S-TGD-1-PA, called glycocardiolipin (GlyC ...

Decoding the Hot‐Mitochondrion Paradox

BioEssays, Volume 48, Issue 7, July 2026.
A distributed mechanism of mitochondrial heat generation is proposed in which all ion‐translocating proteins embedded within the inner mitochondrial membrane contribute to localized heat generation. All ion‐translocating proteins embedded within the inner mitochondrial membrane (IMM)—with ATP synthase shown here as an example—are proposed to function ...

Large scale preparation of homogeneous bacteriorhodopsin [PDF]

, 1990
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.

Scotty: lattice coincidences in the Protein Data Bank

Acta Crystallographica Section D, Volume 82, Issue 7, Page 824-835, July 2026.
Scotty supports crystallographic comparisons of lattice coincidences, the interpretation of oligomeric assemblies and paracrystallinity.The application Scotty, implemented within the Phasertng codebase, was used to perform a PDB‐wide analysis of lattice coincidences.

Bacteriorhodopsin–ZnO hybrid as a potential sensing element for low-temperature detection of ethanol vapour

Beilstein Journal of Nanotechnology, 2016
Zinc oxide (ZnO) and bacteriorhodopsin (bR) hybrid nanostructures were fabricated by immobilizing bR on ZnO thin films and ZnO nanorods. The morphological and spectroscopic analysis of the hybrid structures confirmed the ZnO thin film/nanorod growth and ...

Es werde Licht! Licht als Antrieb und Regulator in synthetischen Zellen

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Zellen sind Systeme außerhalb des Gleichgewichts, die ihre Eigenschaften in Raum und Zeit regulieren. In biomimetischen synthetischen Zellen bietet Licht eine einzigartige Möglichkeit, Vorgänge räumlich und zeitlich anzutreiben und zu kontrollieren.

Let There be Light! Light as an Engine and Regulator in Synthetic Cells

Angewandte Chemie International Edition, Volume 65, Issue 24, 8 June 2026.
Cells are out‐of‐equilibrium systems that regulate their spatiotemporal features. In biomimetic synthetic cells, light offers a unique way for energizing and regulating events in space and time. This review explores the implementation of light‐responsive tools in synthetic cells to replicate biological functions and enable new bioinspired behaviors ...

Role of internal water molecules in bacteriorhodopsin [PDF]

, 2000
Internal water molecules are considered to play a crucial role in the functional processes of proton pump proteins. They may participate in hydrogen-bonding networks inside proteins that constitute proton pathways.
