Bacterial chromosomes are tightly packed in the cells due to interactions with specific nucleoid-associated proteins. Among them, the IHF protein draws attention due to its presumed influence on intracellular crystallization processes, leading to bacterial resistance to drugs. The crystal structure of the IHF heterodimer is known only in complex with a short DNA fragment, whereas ...

The oligomeric state of the nucleoid-associated protein IHF (integration host factor) plays a significant role in the organization and compaction of the bacterial nucleoid and also in the evolution of bacterial resistance to unfavorable environmental conditions, in particular to antibiotics. Although IHF was identified more than 25 years ago, the molecular mechanisms of its participation ...

The DNA-binding protein Dps plays a key role in the formation of Dps–DNA crystalline arrays in living bacterial cells, which allows bacteria to survive under stress conditions and under the influence of various adverse factors. Such genome-protective mechanisms can lead to the emergence of bacterial resistance to antibiotics and other drugs. Elucidation of the fundamental ...

We develop a new quantitative molecular theory of liquid-phase dipolar polymer gels. We model monomer units of the polymer network as a couple of charged sites separated by a fluctuating distance. For the first time, within the random phase approximation, we have obtained an analytical expression for the electrostatic free energy of the dipolar gel. ...

The acylation of unsymmetrical N-benzylbispidinols in aromatic solvents without an external base led to the formation of supramolecular gels, which possess different thicknesses and degrees of stability depending on the substituents in para-positions of the benzylic group as well as on the nature of the acylating agent and of the solvent used. Structural features of the ...

Hydrothermal crystallization pathways of amorphous ceric phosphate gels were found to be determined by the ammonia concentration in a reaction medium. This allows for highly selective hydrothermal synthesis of various finely crystalline ceric phosphates, including Ce(PO4)(HPO4)0.5(H2O)0.5, (NH4)2Ce(PO4)2(H2O), and previously unknown NH4Ce2(PO4)3. The structure of the latter compound was solved from powder X-ray diffraction data. It appeared to be isostructural to ammonium thorium ...
