Hyperplectonemes: A Higher Order Compact and Dynamic DNA Self-Organization

Giovanni Dietler, Paolo De Los Rios, Giovanni Longo, Fabrizio Benedetti, Aleksandre Japaridze

Bacterial chromosome has a compact structure that dynamically changes its shape in response to bacterial growth rate and growth phase. Determining how chromatin remains accessible to DNA binding proteins, and transcription machinery is crucial to understan ...

Male-killing symbiont damages host's dosage-compensated sex chromosome to induce embryonic apoptosis

Bruno Lemaitre, Toshiyuki Harumoto

Some symbiotic bacteria are capable of interfering with host reproduction in selfish ways. How such bacteria can manipulate host's sex-related mechanisms is of fundamental interest encompassing cell, developmental and evolutionary biology. Here, we uncover ...

Telomere functions grounding on TERRA firma

Joachim Lingner

Long noncoding telomeric repeat-containing RNAs TERRAs - are transcribed in a regulated manner from telomeres throughout eukaryotes. TERRA molecules consist of chromosome end-specific subtelomeric sequences and telomeric repeats at their 3' ends. Recent wo ...

NAR Breakthrough Article Crystal structure of Hop2-Mnd1 and mechanistic insights into its role in meiotic recombination

Matteo Dal Peraro, Alexandra Styliani Kalantzi

In meiotic DNA recombination, the Hop2-Mnd1 complex promotes Dmc1-mediated single-stranded DNA (ssDNA) invasion into homologous chromosomes to form a synaptic complex by a yet-unclear mechanism. Here, the crystal structure of Hop2-Mnd1 reveals that it form ...

Effects of physiological self-crowding of DNA on shape and biological properties of DNA molecules with various levels of supercoiling

Giovanni Dietler, Julien Dorier, Fabrizio Benedetti, Yannis Burnier, Aleksandre Japaridze, Andrzej Stasiak, Robert Sebastian Kwapich

DNA in bacterial chromosomes and bacterial plasmids is supercoiled. DNA supercoiling is essential for DNA replication and gene regulation. However, the density of supercoiling in vivo is circa twice smaller than in deproteinized DNA molecules isolated from ...

Functional Dissection of Intersubunit Interactions in the EspR Virulence Regulator of Mycobacterium tuberculosis

Giovanni Dietler, Stewart Cole, Aleksandre Japaridze, Matteo Dal Peraro, Florence Pojer, Marco Stenta, Benjamin Blasco, Basile Isidore Martin Wicky

The nucleoid-associated protein EspR, a chromosome organizer, has pleiotropic effects on expression of genes associated with cell wall function and pathogenesis in Mycobacterium tuberculosis. In particular, EspR binds to several sites upstream of the espAC ...

Replication of Telomeres and the Regulation of Telomerase

Joachim Lingner, Verena Pfeiffer

Telomeres are the physical ends of eukaryotic chromosomes. They protect chromosome ends from DNA degradation, recombination, and DNA end fusions, and they are important for nuclear architecture. Telomeres provide a mechanism for their replication by semico ...
