Journal ArticleDOI
Biodiversity of cryopegs in permafrost
David Gilichinsky,Elizaveta Rivkina,Corien Bakermans,V. A. Shcherbakova,Lada E. Petrovskaya,Svetlana Ozerskaya,N.E. Ivanushkina,G. A. Kochkina,Kyastus Laurinavichuis,Svetlana Pecheritsina,Rushania Fattakhova,James M. Tiedje +11 more
TL;DR: The biodiversity of the indigenous microbial community in the sodium-chloride water brines (cryopegs) derived from ancient marine sediments and sandwiched within permafrost 100-120,000 years ago after the Arctic Ocean regression is described.
Journal ArticleDOI
Biogeochemistry of methane and methanogenic archaea in permafrost
Elizaveta Rivkina,V. A. Shcherbakova,Kestas Laurinavichius,Lada E. Petrovskaya,Kirill Krivushin,Gleb Kraev,Svetlana Pecheritsina,David Gilichinsky +7 more
TL;DR: These findings confirm the presence of methane in permanently frozen fine-grained sediments, and indicate that the process of CH(4) formation is accompanied by the substantial fractionation of carbon isotopes.
Journal ArticleDOI
Lipid-protein nanodiscs for cell-free production of integral membrane proteins in a soluble and folded state: comparison with detergent micelles, bicelles and liposomes.
Ekaterina N. Lyukmanova,Zakhar O. Shenkarev,Nelli F Khabibullina,Nelli F Khabibullina,Gelina S. Kopeina,Gelina S. Kopeina,Mikhail A. Shulepko,Alexander S. Paramonov,Konstantin S. Mineev,R. V. Tikhonov,L. N. Shingarova,Lada E. Petrovskaya,Dmitry A. Dolgikh,Dmitry A. Dolgikh,Alexander S. Arseniev,Mikhail P. Kirpichnikov,Mikhail P. Kirpichnikov +16 more
TL;DR: In this article, lipid-protein nanodiscs (LPNs) of different lipid compositions were compared with classical membrane mimicking media such as detergent micelles, lipid/detergent bicelles and liposomes by their ability to support CF synthesis of integral membrane proteins in a folded and soluble state.
Journal ArticleDOI
Structural insights into the proton pumping by unusual proteorhodopsin from nonmarine bacteria
Ivan Gushchin,Pavel Chervakov,Pavel Kuzmichev,Alexander Popov,Ekaterina Round,Ekaterina Round,Ekaterina Round,Valentin Borshchevskiy,Andrii Ishchenko,Lada E. Petrovskaya,V. A. Chupin,Dmitry A. Dolgikh,Dmitry A. Dolgikh,Alexander S. Arseniev,Mikhail P. Kirpichnikov,Mikhail P. Kirpichnikov,Valentin Gordeliy +16 more
TL;DR: The presented structure sheds light on the large family of proteorhodopsins, for which structural information was not available previously, and the positions of water molecule and amino acid side chains in the immediate Schiff base vicinity are very well conserved.
Journal ArticleDOI
Cloning, purification, and characterization of a cold-adapted esterase produced by Psychrobacter cryohalolentis K5T from Siberian cryopeg.
TL;DR: Activity assay conducted at different temperatures revealed that EstPc is a cold-adapted esterase which possesses relatively high thermostability, preserving more than 60% of activity after incubation for 1 h at 80 °C.
