Characterization of novel mevalonate kinases from the tardigrade Ramazzottius varieornatus and the psychrophilic archaeon Methanococcoides burtonii

Acta Crystallographica Section D, Volume 80, Issue 3, Page 203-215, March 2024.
This work reports the purification, biochemical characterization and high‐resolution structures of two novel mevalonate kinases: one from the extremotolerant tardigrade Ramazzottius varieornatus at 2 Å resolution and one from the psychrophilic archaeon Methanococcoides burtonii at 2.2 Å resolution.Mevalonate kinase is central to the isoprenoid ...

Nucleotide Second Messenger-Based Signaling in Extreme Acidophiles of the Acidithiobacillus Species Complex: Partition Between the Core and Variable Gene Complements

Frontiers in Microbiology, 2019
Cyclic and linear nucleotides are key elements of the signal transduction networks linking perception of the environment to specific cellular behavior of prokaryotes. These molecular mechanisms are particularly important in bacteria exposed to different,

Enhanced chaotrope tolerance and (S)‐2‐hydroxypropiophenone production by recombinant Pseudomonas putida engineered with Pprl from Deinococcus radiodurans

Microbial Biotechnology, Volume 17, Issue 3, March 2024.
The gene encoding the global regulator PprI from Deinococcus radiodurans, an inducer of pleiotropic proteins promoting DNA repair, was expressed in Pseudomonas putida. The cells harbouring the global transcriptional regulator exhibited high tolerance toward benzaldehyde, acetaldehyde, ethanol, butanol, NaCl, H2O2 and thermal stress, thereby reflecting ...

Genome‐scale metabolic modelling of extremophiles and its applications in astrobiological environments

Environmental Microbiology Reports, Volume 16, Issue 1, February 2024.
Metabolic modelling with GEMs is a valuable tool for studying extremophiles and simulating genetic and environmental changes. Integration with other mathematical approaches aids in predicting life forms in astroenvironments, informing the origins of life and space adaptation.

Tolypocladium parasiticum Barron, a polyextremophilic fungus

, 2023
In the past decades, great attention was devoted to extremophilic microorganisms. Extremophiles survive in extreme conditions, such as extreme temperatures, high saline, acidic, and alkaline solutions or environments with increased heavy metal content (1).

A polyextremophilic alcohol dehydrogenase from the Atlantis II Deep Red Sea brine pool [PDF]

FEBS Open Bio, 2018
Enzymes originating from hostile environments offer exceptional stability under industrial conditions and are therefore highly in demand. Using single‐cell genome data, we identified the alcohol dehydrogenase (ADH) gene, adh/a1a, from the Atlantis II Deep Red Sea brine pool. ADH/A1a is highly active at elevated temperatures and high salt concentrations

Concurrent metabolism of pentose and hexose sugars by the polyextremophile Alicyclobacillus acidocaldarius

Journal of Industrial Microbiology and Biotechnology, 2017
Abstract Alicyclobacillus acidocaldarius is a thermoacidophilic bacterium capable of growth on sugars from plant biomass. Carbon catabolite repression (CCR) allows bacteria to focus cellular resources on a sugar that provides efficient growth, but also allows sequential, rather than simultaneous use when more than one sugar is present ...

Efficacy of polyextremophilic Aeribacillus pallidus on bioprocessing of beet vinasse derived from ethanol industries

Bioresource Technology, 2020
This work aimed to evaluate the applicability of Aeribacillus pallidus for the aerobic treatment of the concentrated beet vinasse with high chemical oxygen demand (COD 685 g.L-1) that is defined as an environmental pollutant. This bacterium is a polyextremophilic strain and grow aerobically up to 7.5% vinasse at high temperature (50 °C).

The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

eLife, 2019
The role and extent of horizontal gene transfer (HGT) in eukaryotes are hotly disputed topics that impact our understanding of the origin of metabolic processes and the role of organelles in cellular evolution. We addressed this issue by analyzing 10 novel Cyanidiales genomes and determined that 1% of their gene inventory is HGT-derived.
