Prebiotic Interconversion of Pyruvate and Lactate over Zeolite‐Supported Ni Catalyst

open access: yesAngewandte Chemie, EarlyView.
Synthetic zeolite Y‐supported Ni mineral can catalyze the interconversion of metabolically crucial pyruvate and lactate under hydrothermal vent conditions, which could pave the way for the modern biological process by lactate dehydrogenase and nicotinamide adenine dinucleotide.

Cyclic nucleotides in archaea: Cyclic di‐AMP in the archaeon Haloferax volcanii and its putative role

open access: yesMicrobiologyOpen, 2019
The role of cyclic nucleotides as second messengers for intracellular signal transduction has been well described in bacteria. One recently discovered bacterial second messenger is cyclic di‐adenylate monophosphate (c‐di‐AMP), which has been demonstrated

Identification of XylR, the Activator of Arabinose/Xylose Inducible Regulon in Sulfolobus acidocaldarius and Its Application for Homologous Protein Expression

open access: yesFrontiers in Microbiology, 2020
The thermophilic archaeon Sulfolobus acidocaldarius can use different carbon sources for growth, including the pentoses D-xylose and L-arabinose. In this study, we identified the activator XylR (saci_2116) responsible for the transcriptional regulation ...

Unveiling Structural Heterogeneity and Evolutionary Adaptations of Heteromultimeric Bacterioferritin Nanocages

open access: yesAdvanced Science, EarlyView.
This study explores the structural heterogeneity and evolutionary adaptations of heteromultimeric bacterioferritins. Hetero‐Bfrs, evolved from either a homo‐Bfr or Ftn by gene duplications, differ from homo‐Bfrs substantially in the mechanisms underpinning iron oxidation and reduction despite high similarity in overall structure.

"Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments" [PDF]

open access: yes, 2012
The results obtained in these experiments have revealed a remarkable resistance of extremophilic bacteria and archaea against different radiation sources (VUV, solar wind simulants, X rays) whenever protected by microsized carbonaceus grains. Altogether, the collected data suggest the interesting possibility of the existence of microbial life beyond ...

Structural and Biochemical Characterization of a Widespread Enterobacterial Peroxidase Encapsulin

open access: yesAdvanced Science, EarlyView.
Encapsulins are self‐assembling bacterial protein compartments loaded with cargo enzymes. The most abundant encapsulin cargo class are Dye‐decolorizing Peroxidases (DyPs). In this study, we structurally and biochemically characterize a DyP encapsulin found in many enterobacteria.
