Journal ArticleDOI
The nucleoid protein Dps binds genomic DNA of Escherichia coli in a non-random manner
S. S. Antipov,Maria N. Tutukina,E. V. Preobrazhenskaya,Fyodor A. Kondrashov,Fyodor A. Kondrashov,Maksim Patrushev,Stepan V. Toshchakov,I. N. Dominova,Uliana Shvyreva,V. V. Vrublevskaya,O. S. Morenkov,N. A. Sukharicheva,Valeriy V. Panyukov,Valeriy V. Panyukov,Olga N. Ozoline +14 more
TL;DR: A non-random distribution of Dps binding sites across the bacterial chromosome in exponentially growing cells is reported and it is found that the Dps-bound regions overlap with sites occupied by other nucleoid proteins, and contain overrepresented motifs typical for their consensus sequences.
Journal ArticleDOI
Hexuronates influence the oligomeric form of the Dps structural protein of bacterial nucleoid and its ability to bind to linear DNA fragments
T. A. Bessonova,T. A. Bessonova,S. A. Shumeiko,Yu. A. Purtov,S. S. Antipov,E. V. Preobrazhenskaya,E. V. Preobrazhenskaya,Maria N. Tutukina,Olga N. Ozoline +8 more
TL;DR: The consequent destabilization of the intersubunit bonding network can, thus, be the main factor provoking the protein decay to the smaller oligomeric forms, and may play a key role in genome decondensation during cell transition to the phase of rapid growth.
Journal ArticleDOI
High resolution cryogenic transmission electron microscopy study of Escherichia coli Dps protein: First direct observation in quasinative state
S.S. Antipov,S.S. Antipov,E.B. Pichkur,N.V. Praslova,E. V. Preobrazhenskaya,D. S. Usoltseva,E.A. Belikov,O. A. Chuvenkova,M. Yu. Presnyakov,Valeriy Artyukhov,Olga N. Ozoline,S. Yu. Turishchev +11 more
TL;DR: In this paper, high resolution cryogenic transmission electron microscopy was applied to visualize the protein molecules and to characterize their ability to self-organization, and highly ordered two-dimensional layers with hexagonal symmetry were obtained.
Journal ArticleDOI
On the possibility of PhotoEmission Electron Microscopy for E. coli advanced studies
S. Yu. Turishchev,Dmitry Marchenko,Vladimir Sivakov,E.A. Belikov,O. A. Chuvenkova,E. V. Parinova,D. A. Koyuda,R.G. Chumakov,A.M. Lebedev,T.V. Kulikova,A.A. Berezhnoy,I.V. Valiakhmedova,N.V. Praslova,E. V. Preobrazhenskaya,S.S. Antipov,S.S. Antipov +15 more
TL;DR: In this article, a novel approach was proposed for detailed high-resolution studies of morphology and physico-chemical properties concomitantly at one measurement spot of E. coli bacterial cells.
