Structural Dynamics of Archaeal Small Heat Shock Proteins
Journal of Molecular Biology, 2008Small heat shock proteins (sHsps) are a widespread and diverse class of molecular chaperones. In vivo, sHsps contribute to thermotolerance. Recent evidence suggests that their function in the cellular chaperone network is to maintain protein homeostasis by complexing a variety of non-native proteins.

Functions of Archaeal Nucleoid Proteins: Archaeal Silencers are Still Missing
2019It is well known that horizontally transferred genes (HTGs) contribute to the adaptation of archaea to their living environment. Archaea have acquired HTGs not only from other archaea but also from bacteria. HTGs should be integrated into the host archaeal transcriptional networks to become functional.

The protein sequence of an archaeal catalase-peroxidase
Biochimie, 1998The gene encoding a catalase-peroxidase of archaeal origin, the halophilic catalase-peroxidase from Haloarcula marismortui, was sequenced. The primary structure proposed was confirmed by Edman degradation and mass spectrometry analyses of proteolytic fragments of the purified protein.

Protein–protein interactions in the archaeal core replisome
Biochemical Society Transactions, 2011Most of the core components of the archaeal chromosomal DNA replication apparatus share significant protein sequence similarity with eukaryotic replication factors, making the Archaea an excellent model system for understanding the biology of chromosome replication in eukaryotes.

Facing extremes: archaeal surface-layer (glyco)proteins
Microbiology, 2003Archaea are best known in their capacities as extremophiles, i.e. micro-organisms able to thrive in some of the most drastic environments on Earth. The protein-based surface layer that envelopes many archaeal strains must thus correctly assemble and maintain its structural integrity in the face of the physical challenges associated with, for instance ...

The Archaeal Sac10b Protein Family: Conserved Proteins with Divergent Functions
Current Protein & Peptide Science, 2012Here we review the present state of structural and functional studies of the Sac10b protein family, a class of highly conserved 10 kDa nucleic acid-binding proteins in archaea. Based on biochemical and structural studies, these proteins were originally assigned a role in the structural organization of chromatin; Sac10b proteins of hyperthermophilic ...

Archaeal DNA Binding Proteins and Chromosome Structure
Systematic and Applied Microbiology, 1993Summary Small, basic, abundant DNA-binding proteins have been isolated from many different prokaryotes. Proteins of this type that have been characterized from Archaea are reviewed here, and their structural and functional relationships to bacterial histone-like proteins and eukaryal histones are discussed. Members of the HMf family of archaeal DNA-

Sec61β – a component of the archaeal protein secretory system
Trends in Biochemical Sciences, 2002Sec61p/SecYEG complexes mediate protein translocation across membranes and are present in both eukaryotes and bacteria. Whereas homologues of Sec61alpha/SecY and Sec61gamma/SecE exist in archaea, identification of the third component (Sec61beta or SecG) has remained elusive. Using PSI-BLAST, the archaeal counterpart of Sec61beta has been detected. With

Archaeal chromatin proteins: different structures but common function?
Current Opinion in Microbiology, 2005Chromatin proteins promote chromosome flexibility in vivo, maintaining a compact yet decondensed template that permits polymerase accessibility. All Archaea have at least two types of chromatin proteins, and diversity in the chromatin protein population appears to prevent polymerization of a single type of protein.
