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 ...

Investigation of the regulatory function of archaeal ribosomal protein L4
Biochemistry (Moscow), 2014Ribosomal protein L4 is a regulator of protein synthesis in the Escherichia coli S10 operon, which contains genes of 11 ribosomal proteins. In this work, we have investigated regulatory functions of ribosomal protein L4 of the thermophilic archaea Methanococcus jannaschii. The S10-like operon from M.

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.

An archaeal chaperonin-based reactor for renaturation of denatured proteins
Extremophiles, 2000We describe an original chaperonin-based reactor that yields folded and active proteins from denatured materials. We used the 920-kDa chaperonin of the archaeon Sulfolobus solfataricus, which does not require any protein partner for its full activity and assists in vitro folding with low substrate specificity. The reactor consists of an ultrafiltration

Overexpression of an archaeal protein in yeast: Secretion bottleneck at the ER
Biotechnology and Bioengineering, 2002AbstractArchaeal enzymes have great potential for industrial use; however, expressing them in their natural hosts has proven challenging. Growth conditions for many archaea are beyond typical fermentation capabilities, and to compound the problem, archaea generally achieve much lower biomass yields than Escherichia coli or Saccharomyces cerevisiae.

Structural characterization of the functional regions in the archaeal protein Sso7d
Proteins: Structure, Function, and Bioinformatics, 2007AbstractSso7d from the extreme thermophilic crenarchaeon Sulfolobus solfataricus is a multifunctional protein in in vitro assays, whose in vivo role is still puzzling. Crystals of Sso7d in complex with DNA elucidated the protein surface involved in the binding to the nucleic acid, whereas the locations of the Sso7d regions responsible for a chaperone ...

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 ...
