Biology Direct, 2010 Primase and GINS are essential factors for chromosomal DNA replication in eukaryotic and archaeal cells. Here we describe a previously undetected relationship between the C-terminal domain of the catalytic subunit (PriS) of archaeal primase and the B ...

Comparative genomics of DNA-binding transcription factors in archaeal and bacterial organisms.
PLoS ONE, 2021 Archaea represent a diverse phylogenetic group that includes free-living, extremophile, mesophile, symbiont, and opportunistic organisms. These prokaryotic organisms share a high significant similarity with the basal transcriptional machinery of Eukarya,

CetZ tubulin-like proteins control archaeal cell shape [PDF]
Nature, 2014 Tubulin is a major component of the eukaryotic cytoskeleton, controlling cell shape, structure and dynamics, whereas its bacterial homologue FtsZ establishes the cytokinetic ring that constricts during cell division. How such different roles of tubulin and FtsZ evolved is unknown.

Identification of Diverse Archaeal Proteins with Class III Signal Peptides Cleaved by Distinct Archaeal Prepilin Peptidases [PDF]
Journal of Bacteriology, 2007 ABSTRACT Most secreted archaeal proteins are targeted to the membrane via a tripartite signal composed of a charged N terminus and a hydrophobic domain, followed by a signal peptidase-processing site. Signal peptides of archaeal flagellins, similar to class III signal peptides of bacterial type IV pilins, are distinct in that ...

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 ...

A Prokaryotic Twist on Argonaute Function
Life, 2015 Argonaute proteins can be found in all three domains of life. In eukaryotic organisms, Argonaute is, as the functional core of the RNA-silencing machinery, critically involved in the regulation of gene expression.

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 ...

Pressures in archaeal protein coding genes: a comparative study [PDF]
Comparative and Functional Genomics, 2003 AbstractOur studies on the bases of codons from 11 completely sequenced archaeal genomes show that, as we move from GC‐rich to AT‐rich protein‐coding gene‐containing species, the differences between G and C and between A and T, the purine load (AG content), and also the overall persistence (i.e.
