Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica

, 2014
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes

Chemistry – A European Journal, EarlyView.
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

Quantitative analysis of amino acid excretion and consumption by Methanothermobacter marburgensis in fed-batch cultivation mode

Amino Acids
The methanogenic archaeon Methanothermobacter marburgensis offers a promising alternative to traditional bacterial systems for the sustainable production of proteinogenic amino acids (AAs), eliminating the need for sugar-based feedstock.

Candidatus Nitrosocaldus cavascurensis, an Ammonia Oxidizing, Extremely Thermophilic Archaeon with a Highly Mobile Genome

Frontiers in Microbiology, 2018
Ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread in moderate environments but their occurrence and activity has also been demonstrated in hot springs. Here we present the first enrichment of a thermophilic representative with a

Hot and crispy : CRISPR-Cas systems in the hyperthermophile Sulfolobus solfataricus

, 2013
The CRISPR (clustered regularly interspaced short palindromic repeats) and Cas (CRISPR-associated) genes are widely spread in bacteria and archaea, representing an intracellular defence system against invading viruses and plasmids.

"Hot standards" for the thermoacidophilic archaeon Sulfolobus solfataricus [PDF]

, 2009
Within the archaea, the thermoacidophilic crenarchaeote Sulfolobus solfataricus has become an important model organism for physiology and biochemistry, comparative and functional genomics, as well as, more recently also for systems biology approaches ...

Spotlight on the Nucleotide: Solid‐State NMR for the Investigation of ATP Hydrolysis in the ATPase SmsC

Chemistry – A European Journal, EarlyView.
Nucleotide‐detected solid‐state NMR has been applied to probe nucleotide conformations and dynamics during ATP hydrolysis using the dimeric P‐loop ATPase SmsC as a model protein. The different stages of ATP hydrolysis have been mimicked by ATP analogues for which different degrees of conformational heterogeneity have been observed. ABSTRACT Solid‐state

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...
