Investigation of the Relationship between the S1 Domain and Its Molecular Functions Derived from Studies of the Tertiary Structure

open access: yesMolecules, 2019
S1 domain, a structural variant of one of the “oldest” OB-folds (oligonucleotide/oligosaccharide-binding fold), is widespread in various proteins in three domains of life: Bacteria, Eukaryotes, and Archaea. In this study, it was shown that S1

Antioxidative and chaperone‐like activities of a bacterioruberin‐rich extract: An innovative approach to protect the skin proteome

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The bacteriorubin‐rich extract of Arthrobacter agilis has high antioxidative properties, protecting proteins against oxidative stress and preventing their carbonylation. It also protects proteins against saline and heat stresses, suggesting a dual mode of action including antioxidant and chaperone‐like activities.

Archaeal histones: dynamic and versatile genome architects

open access: yesAIMS Microbiology, 2015
Genome organization and compaction in Archaea involves different chromatin proteins, among which homologues of eukaryotic histones. Archaeal histones are considered the ancestors of their eukaryotic counterparts, which isreflected in the way they ...

Bacillus subtilis RNase HII Is Inefficient at Processing Guanosine Monophosphate and Damaged Ribonucleotides

open access: yesMolecular Microbiology, EarlyView.
Bacillus subtilis RNase HII corrects ribonucleotide errors and mismatched ribonucleotides, but not damaged ribonucleotides. Mismatched ribonucleotides would also serve as substrates for mismatch repair while damaged ribonucleotides would be addressed through base excision repair.

The Prevalence of STIV c92-Like Proteins in Acidic Thermal Environments

open access: yesAdvances in Virology, 2011
A new type of viral-induced lysis system has recently been discovered for two unrelated archaeal viruses, STIV and SIRV2. Prior to the lysis of the infected host cell, unique pyramid-like lysis structures are formed on the cell surface by the protrusion ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.

Fusion/fission protein family identification in Archaea

open access: yesmSystems
The majority of newly discovered archaeal lineages remain without a cultivated representative, but scarce experimental data from the cultivated organisms show that they harbor distinct functional repertoires.

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Archaeal protein kinases and protein phosphatases: insights from genomics and biochemistry [PDF]

open access: yesBiochemical Journal, 2003
Protein phosphorylation/dephosphorylation has long been considered a recent addition to Nature's regulatory arsenal. Early studies indicated that this molecular regulatory mechanism existed only in higher eukaryotes, suggesting that protein phosphorylation/dephosphorylation had emerged to meet the particular signal-transduction requirements of ...
