Publications related to Self-organization of parS centromeres by the ParB CTP hydrolase

CENP-A and CENP-B collaborate to create an open centromeric chromatin state

Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...

Recycling of Polymerase Chain Reaction (PCR) Kits

Francesco Stellacci, Yong Zhu, Weina Liu

Polymerase chain reaction (PCR) kits have been used as common diagnosing tools during the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with daily worldwide usage in the millions. It is well known that at the beginn ...

Computational Studies for the Design of Metalloenzyme Mimics

Guido Frisari

At present, there is no general standard automated method for engineering metalloenzymes, industrially-relevant systems able to catalyze environmentally friendly reactions. One of the most studied natural metalloenzymes is the second isoform of human carbo ...

Relief of ParB autoinhibition by parS DNA catalysis and recycling of ParB by CTP hydrolysis promote bacterial centromere assembly

Paolo De Los Rios, Stefano Zamuner

Three-component ParABS systems are widely distributed factors for plasmid partitioning and chromosome segregation in bacteria. ParB acts as adaptor protein between the 16-base pair centromeric parS DNA sequences and the DNA segregation proteins ParA and Sm ...

Shear Stress-Responsive Polymersome Nanoreactors Inspired by the Marine Bioluminescence of Dinoflagellates

Esther Amstad, Antoine Claude Jean Vian

Some marine plankton called dinoflagellates emit light in response to the movement of surrounding water, resulting in a phenomenon called milky seas or sea sparkle. The underlying concept, a shear-stress induced permeabilisation of biocatalytic reaction co ...

Nuclear RNR-alpha antagonizes cell proliferation by directly inhibiting ZRANB3

Yuan Fu, Yimon Aye

Since the origins of DNA-based life, the enzyme ribonucleotide reductase (RNR) has spurred proliferation because of its rate-limiting role in de novo deoxynucleoside-triphosphate (dNTP) biosynthesis. Paradoxically, the large subunit, RNR-alpha, of this obl ...

Role of Environment for Catalysis of the DNA Repair Enzyme MutY

Ursula Röthlisberger, Jeremy Samuel Arey, Elizabeth Claire Brunk

Control of the N-glycosylase reaction by the DNA repair enzyme, MutY, entails the organization of solvent molecules. Classical molecular dynamics and QM/MM simulations were used to investigate the solvent and environment effects contributing to catalysis. ...

Controlling a Single DNA Molecule in an Electric Field by Means of In Situ Atomic Force Microscopy

Giovanni Dietler, Jae Sun Jeong

DNA is the bio-polymer containing the genetic information needed for the development and functioning for all living organisms. It has a polymeric structure consisting of units called nucleotides, each consisting of a non-polar, hydrophobic interior (the ba ...

The Interplay between Cytidine Deaminases, HIV and Domesticated Genetic Parasites

"There is more virus in us than us in us". John Coffin's famous sentence illustrates that particular nucleic acid sequences related to exogenous viruses, called retrotransposons, constitute almost half of the human genome and largely exceeds the amount of ...

Modified short interfering RNA

Luc Reymond, Evelyne Muller

The present invention refers to a double-stranded siRNA molecule comprising a sense Strand and an antisense Strand which is essentially complementary to the sense Strand, each of the sense and the antisense Strands comprising at least 17 nucleotides (nt), ...

Optimized methods for the enzymatic ligation of oligoribonucleotides and analogues

Frédéric David Meylan

The preparation of oligoribonucleotides is of great interest for structural and functional investigations in biomolecular chemistry and biology. Relevant RNAs are relatively long and contain often modifications. Two methods for their preparation are curren ...
