Biochemical evidence for an alternate pathway in N-linked glycoprotein biosynthesis [PDF]

, 2012
Asparagine-linked glycosylation is a complex protein modification conserved among all three domains of life. Herein we report the in vitro analysis of N-linked glycosylation from the methanogenic archaeon Methanococcus voltae.

Differential Expression of Core Metabolic Functions in Candidatus Altiarchaeum Inhabiting Distinct Subsurface Ecosystems

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Major differences between Candidatus Altiarchaeum species living in two distinct subsurface ecosystems as determined via metatranscriptomics. Genes overly expressed in different Ca. Altiarchaea in Muehlbacher sufidic spring (magenta; MSI; Regensburg, Germany) and Crystal Geyser (turquise; CG; Utah, USA). Ca.

Subunit Topology of Two 20S Proteasomes from Haloferax volcanii [PDF]

Journal of Bacteriology, 2003
ABSTRACT Haloferax volcanii , a halophilic archaeon, synthesizes three different proteins (α1, α2, and β) which are classified in the 20S proteasome superfamily. The α1 and β proteins alone form active 20S proteasomes; the role of α2, however, is not clear.

tRNA splicing [PDF]

, 1998
Introns interrupt the continuity of many eukaryal genes, and therefore their removal by splicing is a crucial step in gene expression. Interestingly, even within Eukarya there are at least four splicing mechanisms.

Non‐conserved microRNAs and their roles in plants: the case for legumes

Plant Biology, Volume 27, Issue 4, Page 450-460, June 2025.
Non‐conserved miRNAs are functional and modulate stress and microbial interactions in legumes, hinting at broader roles in plant gene regulation. Abstract Several classes of small RNAs function to regulate stress and development pathways in all kingdoms of life.

Structure-function relationships of archaeal Cbf5 during in vivo RNA-guided pseudouridylation. [PDF]

, 2016
In Eukarya and Archaea, in addition to protein-only pseudouridine (Ψ) synthases, complexes containing one guide RNA and four proteins can also produce Ψ. Cbf5 protein is the Ψ synthase in the complex.

How Small Proteins Adjust the Metabolism of Cyanobacteria Under Stress

BioEssays, Volume 47, Issue 3, March 2025.
Cyanobacteria are powered by oxygenic photosynthesis located in extensive internal membrane systems, the thylakoids. Using carboxysomes, they assimilate organic from inorganic carbon. The integration of photosynthesis, carbon fixation, assimilation of nitrogen, and other nutrients involves several small proteins.

Rings in the Extreme: PCNA Interactions and Adaptations in the Archaea [PDF]

, 2012
Biochemical and structural analysis of archaeal proteins has enabled us to gain great insight into many eukaryotic processes, simultaneously offering fascinating glimpses into the adaptation and evolution of proteins at the extremes of life. The archaeal

Distinct Patterns of Antibiotic Sensitivities in Ammonia‐Oxidising Archaea

Environmental Microbiology, Volume 27, Issue 3, March 2025.
Antibiotic sensitivity varies between different strains of ammonia‐oxidising archaea. The results of this study will be useful for selective enrichment and development of a genetic system for ammonia‐oxidising archaea. ABSTRACT Ammonia‐oxidising archaea (AOA) are important microorganisms contributing towards the nitrogen flux in the environment. Unlike

Structural features of halophilicity derived from the crystal structure of dihydrofolate reductase from the Dead Sea halophilic archaeon, Haloferax volcanii [PDF]

, 1982
Background: The proteins of halophilic archaea require high salt concentrations both for stability and for activity, whereas they denature at low ionic strength. The structural basis for this phenomenon is not yet well understood.
