Structural studies of bacteriorhodopsin in BC era

open access: yesBiophysics and Physicobiology, 2023
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,

Detection of second-order nonlinear optical magnetization by mapping normalized Stokes parameters [PDF]

open access: yes, 2013
A measurable magnetic (nonlocal) contribution to the second harmonic generation (SHG) of nonmagnetic materials is an intriguing issue related to chiral materials, such as biomolecules.

Precise Capture of Membrane Proteins Using DNA‐Origami‐Constrained Nanodiscs

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
A designed DNA origami structure ensures manipulates and inserts an individual membrane protein in a single, captured nanodisc. Membrane proteins play a key role as cellular gatekeepers, regulating the flow of information and material across lipid membranes.

Comparative analysis of canonical and noncanonical rhodopsins in Amphidinium carterae and Karlodinium veneficum

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 360-376, April 2026.
Abstract Rhodopsins are ancient and versatile light‐sensitive proteins, widely distributed across microbial life. In dinoflagellates, however, their diversity and function remain poorly understood, owing to the lineage's extreme genomic divergence. Here, we surveyed the rhodopsin complements of two dinoflagellates, Amphidinium carterae and Karlodinium ...

Hierarchy and assortativity as new tools for affinity investigation: the case of the TBA aptamer-ligand complex

open access: yes, 2017
Aptamers are single stranded DNA, RNA or peptide sequences having the ability to bind a variety of specific targets (proteins, molecules as well as ions).

Halide binding by the purified halorhodopsin chromoprotein. II. New chloride-binding sites revealed by 35Cl NMR [PDF]

open access: yes, 1984
Halorhodopsin is a light-driven chloride pump in the cell membrane of Halobacterium halobium. Recently, a polypeptide of apparent Mr = 20,000 has been purified that contains the halorhodopsin chromophore.

Biomolecular imaging and electronic damage using X-ray free-electron lasers

open access: yes, 2010
Proposals to determine biomolecular structures from diffraction experiments using femtosecond X-ray free-electron laser (XFEL) pulses involve a conflict between the incident brightness required to achieve diffraction-limited atomic resolution and the ...

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...
