DNA supercoiling and transcription in bacteria: a two-way street
BMC Molecular and Cell Biology, 2019 Background The processes of DNA supercoiling and transcription are interdependent because the movement of a transcription elongation complex simultaneously induces under- and overwinding of the DNA duplex and because the initiation, elongation and ...

Chromosome segregation in a minimal bacterial cell driven by SMC protein complexes
Protein Science, Volume 35, Issue 6, June 2026.Abstract Minimal bacterial cells such as JCVI‐Syn3A provide a powerful system for uncovering the essential mechanisms of chromosome organization and segregation. Lacking canonical systems such as Min and ParABS, JCVI‐Syn3A relies primarily on structural maintenance of chromosomes (SMC) protein complexes for partitioning.

, 2016 In higher organisms, all cells share the same genome, but every cell expresses only a limited and specific set of genes that defines the cell type. During cell division, not only the genome, but also the cell type is inherited by the daughter cells. This

Elastic Rod Model of a Supercoiled DNA Molecule
, 2000 We study the elastic behaviour of a supercoiled DNA molecule. The simplest model is that of a rod like chain, involving two elastic constants, the bending and the twist rigidities.

Current Protocols, Volume 6, Issue 5, May 2026.Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.

Evolution, Adaptation, and Supercoiling [PDF]
Journal of Bacteriology, 2007 Geometrical and, to some extent, physical and informational properties of covalently closed DNA molecules (or molecules that can be ideally viewed as closed) are determined by their connectivity, i.e., the number of times one strand of DNA is topologically linked to another.

BMC Microbiology, 2002 Background When Bacillus subtilis is cultured in a complex fluid medium under conditions where cell separation is suppressed, populations of multicellular macrofibers arise that mature into ball-like structures.

Supercoiling in DNA and chromatin
Current Opinion in Genetics & Development, 2014 Supercoiling is a fundamental property of DNA and chromatin. It is modulated by polymerase and topoisomerase activities and, through regulated constraint, by DNA/chromatin binding proteins. As a non-covalent and elusive topological modification, supercoiling has proved intractable to research despite being a crucial regulator of nuclear structure and ...
