Diversity of DNA replication in the archaea [PDF]

, 2017
DNA replication is arguably the most fundamental biological process. On account of their shared evolutionary ancestry, the replication machinery found in archaea is similar to that found in eukaryotes.

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

, 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.

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

The Role of Polyphosphate in Motility, Adhesion, and Biofilm Formation in Sulfolobales

Microorganisms, 2021
Polyphosphates (polyP) are polymers of orthophosphate residues linked by high-energy phosphoanhydride bonds that are important in all domains of life and function in many different processes, including biofilm development. To study the effect of polyP in

High-affinity RNA binding by a hyperthermophilic single-stranded DNA-binding protein [PDF]

, 2017
Single-stranded DNA-binding proteins (SSBs), including replication protein A (RPA) in eukaryotes, play a central role in DNA replication, recombination, and repair. SSBs utilise an oligonucleotide/oligosaccharide-binding (OB) fold domain to bind DNA, and

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Efficient CRISPR-Mediated Post-Transcriptional Gene Silencing in a Hyperthermophilic Archaeon Using Multiplexed crRNA Expression

G3: Genes, Genomes, Genetics, 2016
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-mediated RNA degradation is catalyzed by a type III system in the hyperthermophilic archaeon Sulfolobus solfataricus. Earlier work demonstrated that the system can be engineered to target

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, Volume 599, Issue 23, Page 3417-3443, December 2025.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...
