DPANN archaea [PDF]

Current Biology
Archaea are one of the two primary domains of life alongside Bacteria. Extant archaea play an important role in global nutrient cycles and comprise members that were crucial for the evolution of life on Earth including the origin of eukaryotic cells through a symbiotic integration of an archaeal and bacterial partner.

Archaea [PDF]

, 2021
In agreement with their close relationship to eukaryotes, Archaea encode informational processing machineries that closely resemble those of eukaryotic representatives. The composition of archaeal cell membranes differs fundamentally from those of Bacteria and eukaryotes.

Features of Aminoacyl-tRNA Synthesis Unique to Archaea [PDF]

, 2007
This chapter discusses four unique aspects of archaeal aa‐tRNA formation that led to a much deeper understanding of this process not only in the Archaea, but in all domains of life.

The transcriptional regulator EarA and intergenic terminator sequences modulate archaellation in Pyrococcus furiosus

Frontiers in Microbiology, 2023
The regulation of archaellation, the formation of archaeal-specific cell appendages called archaella, is crucial for the motility, adhesion, and survival of archaeal organisms.

Deep Learning Enables Identification of Antimicrobial Peptides Through Mechanochromic Fingerprints

Angewandte Chemie, EarlyView.
We demonstrate a new platform for antimicrobial peptide identification by combining polydiacetylene, hyperspectral imaging, and deep learning. The trained model classifies distinct spectral fingerprints into 14 peptide classes with 96.79% accuracy, revealing previously hidden molecular information beyond conventional colorimetric sensing.

Diversity and Spatial Distribution of Prokaryotic Communities Along A Sediment Vertical Profile of A Deep-Sea Mud Volcano Maria G. Pachiadaki & Argyri Kallionaki [PDF]

, 2011
We investigated the top 30-cm sediment prokaryotic community structure in 5-cm spatial resolution, at an active site of the Amsterdam mud volcano, East Mediterranean Sea, based on the 16S rRNA gene diversity.

Enzymatic Switching Between Archaeal DNA Polymerases Facilitates Abasic Site Bypass

Frontiers in Microbiology, 2021
Abasic sites are among the most abundant DNA lesions encountered by cells. Their replication requires actions of specialized DNA polymerases. Herein, two archaeal specialized DNA polymerases were examined for their capability to perform translesion DNA ...

Prefoldins in Archaea

, 2018
Molecular chaperones promote the correct folding of proteins in aggregation-prone cellular environments by stabilizing nascent polypeptide chains and providing appropriate folding conditions. Prefoldins (PFDs) are molecular chaperones found in archaea and eukaryotes, generally characterized by a unique jellyfish-like hexameric structure consisting of a
