Free energy profile for unwrapping outer superhelical turn of CENP-A nucleosome
Biophysics and Physicobiology, 2019 Eukaryotic genome is packaged in a nucleus in the form of chromatin. The fundamental structural unit of the chromatin is the protein-DNA complex, nucleosome, where DNA of about 150 bp is wrapped around a histone core almost twice.

3D Printing of Conducting Polymer Hydrogels for Electrostimulation‐Assisted Tissue Engineering
Advanced Materials, Volume 37, Issue 36, September 11, 2025.This review highlights nanosized inherently conducting polymers (ICPs) as promising ink constituents for 3D printing of conducting hydrogel (CH)‐based electrostimulation (ES) devices. ICP‐based ink formulation, 3D printing, and solidification strategies are discussed, along with the application of 3D‐printed ICP‐based CHs as ES platforms for regulating

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 9, Page 1465-1480, September 2025.ABSTRACT ZraS is a metal sensor integral to ZraPSR, a two‐component signaling system found in enterobacters. It belongs to a family of bifunctional sensor histidine kinases (SHKs) and is speculated to sense zinc‐induced stress on the bacterial envelope.

Hopping into a hot seat: Role of DNA structural features on IS5-mediated gene activation and inactivation under stress. [PDF]
PLoS ONE, 2017 Insertion sequence elements (IS elements) are proposed to play major roles in shaping the genetic and phenotypic landscapes of prokaryotic cells. Recent evidence has raised the possibility that environmental stress conditions increase IS hopping into new

A pH-dependent structural transition in the homopurine-homopyrimidine tract in superhelical DNA.
Journal of Biomolecular Structure and Dynamics, 1985 We have inserted the 509-bp-long fragment of sea urchin P. miliaris histone gene spacer region into plasmid pUC19. The fragment contains the 60-bp-long homopurine-homopyrimidine tract that is known to be hypersensitive to the S1 endonuclease.

Circularly polarized luminescence from supramolecular assemblies based on small molecules
Smart Molecules, Volume 3, Issue 3, September 2025.This minireview outlines the recent advances of circularly polarized luminescence (CPL)‐active supramolecular assemblies based on small molecules. It covers fundamental concepts of CPL, typical design strategies of CPL‐active materials—including the assembly of chiral luminophores, the assembly of chiral components and achiral luminophores, and the ...
