Archaeal S-Layers: Overview and Current State of the Art
Frontiers in Microbiology, 2017 In contrast to bacteria, all archaea possess cell walls lacking peptidoglycan and a number of different cell envelope components have also been described.

The Archaeal Lsm Protein Binds to Small RNAs [PDF]
Journal of Biological Chemistry, 2010 Proteins of the Lsm family, including eukaryotic Sm proteins and bacterial Hfq, are key players in RNA metabolism. Little is known about the archaeal homologues of these proteins. Therefore, we characterized the Lsm protein from the haloarchaeon Haloferax volcanii using in vitro and in vivo approaches. H.

The archaeal Sec–dependent protein translocation pathway [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2004 Over the past three decades, transport of proteins across cellular membranes has been studied extensively in various model systems. One of the major transport routes, the so–called Sec pathway, is conserved in all domains of life. Very little is known about this pathway in the third domain of life, archaea.

An archaeal homolog of proteasome assembly factor functions as a proteasome activator. [PDF]
PLoS ONE, 2013 Assembly of the eukaryotic 20S proteasome is an ordered process involving several proteins operating as proteasome assembly factors including PAC1-PAC2 but archaeal 20S proteasome subunits can spontaneously assemble into an active cylindrical ...

Adaptations of archaeal and bacterial membranes to variations in temperature, pH and pressure
Extremophiles, 2017 The cytoplasmic membrane of a prokaryotic cell consists of a lipid bilayer or a monolayer that shields the cellular content from the environment. In addition, the membrane contains proteins that are responsible for transport of proteins and metabolites ...

Archaeal protein translocation [PDF]
European Journal of Biochemistry, 2000 Proper cell function relies on correct protein localization. As a first step in the delivery of extracytoplasmic proteins to their ultimate destinations, the hydrophobic barrier presented by lipid‐based membranes must be overcome. In contrast to the well‐defined bacterial and eukaryotic protein translocation systems, little is known about how proteins ...

DNA-Interacting Characteristics of the Archaeal Rudiviral Protein SIRV2_Gp1 [PDF]
Viruses, 2017 Whereas the infection cycles of many bacterial and eukaryotic viruses have been characterized in detail, those of archaeal viruses remain largely unexplored. Recently, studies on a few model archaeal viruses such as SIRV2 (Sulfolobus islandicus rod-shaped virus) have revealed an unusual lysis mechanism that involves the formation of pyramidal egress ...

The crystal structure of Haloferax volcanii proliferating cell nuclear antigen reveals unique surface charge characteristics due to halophilic adaptation [PDF]
, 2009 Background: The high intracellular salt concentration re quired to maintain a halophilic lifestyle poses challenges to haloarchaeal proteins that must stay soluble, stable and functional in this extreme environment.
