Protein phosphorylation and its role in archaeal signal transduction [PDF]

open access: yesFEMS Microbiology Reviews, 2016
Reversible protein phosphorylation is the main mechanism of signal transduction that enables cells to rapidly respond to environmental changes by controlling the functional properties of proteins in response to external stimuli. However, whereas signal transduction is well studied in Eukaryotes and Bacteria, the knowledge in Archaea is still rather ...

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

open access: yesAdvanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Protein acetylation in archaea, bacteria, and eukaryotes [PDF]

open access: yes, 2010
Proteins can be acetylated at the alpha-amino group of the N-terminal amino acid (methionine or the penultimate amino acid after methionine removal) or at the epsilon-amino group of internal lysines.

Genomic Inference of the Metabolism and Evolution of the Archaeal Phylum Aigarchaeota [PDF]

open access: yes, 2018
Microbes of the phylum Aigarchaeota are widely distributed in geothermal environments, but their physiological and ecological roles are poorly understood.

A YidC-like Protein in the Archaeal Plasma Membrane [PDF]

open access: yesStructure, 2015
Cells possess specialized machinery to direct the insertion of membrane proteins into the lipid bilayer. In bacteria, the essential protein YidC inserts certain proteins into the plasma membrane, and eukaryotic orthologs are present in the mitochondrial inner membrane and the chloroplast thylakoid membrane.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

open access: yesAdvanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Regulatory sequence-based discovery of anti-defense genes in archaeal viruses

open access: yesNature Communications
In silico identification of viral anti-CRISPR proteins (Acrs) has relied largely on the guilt-by-association method using known Acrs or anti-CRISPR associated proteins (Acas) as the bait.

Resurrecting the Activity of the RNA Subunit of Human RNase P. [PDF]

open access: yesChembiochem
The catalytic RNA (H1 RNA) of the human nuclear tRNA processing enzyme RNase P has >105‐fold lower activity in the absence of its 11 protein cofactors than bacterial RNase P RNAs. By introducing mutations toward the bacterial consensus into its catalytic domain, a two and fivefold activity enhancement could be achieved by changes in the P4‐19/4 region ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

open access: yesAnimal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

DNA interference and beyond: structure and functions of prokaryotic Argonaute proteins

open access: yesNature Communications, 2018
In this review, Aravin and colleagues examine bacterial and archaeal Argonaute proteins, discuss their diverse architectures and their possible roles in host defense, proposing additional functions for Argonaute proteins in prokaryotic cells.
