DIVERSITY AND EVOLUTION OF TYPE IV PILI SYSTEMS IN ARCHAEA
Frontiers in Microbiology, 2016 Many surface structures in archaea including various types of pili and the archaellum (archaeal flagellum) are homologous to bacterial type IV pili systems (T4P).

Crystal structure of an archaeal CorB magnesium transporter
Nature Communications, 2021 CNNM/CorB proteins are a conserved family of membrane proteins associated with Mg2+ transport. Here, structures of an archaeal CorB protein in apo state and with Mg2+-ATP bound and accompanying biophysical experiments suggest direct Mg2+ transport by ...

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.

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.

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,

Identification of an ortholog of the eukaryotic RNA polymerase III subunit RPC34 in Crenarchaeota and Thaumarchaeota suggests specialization of RNA polymerases for coding and non-coding RNAs in Archaea. [PDF]
, 2009 Contains fulltext : 80405.pdf (Publisher’s version ) (Open Access)One of the hallmarks of eukaryotic information processing is the co-existence of 3 distinct, multi-subunit RNA polymerase complexes that are dedicated to the ...

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 ...

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.
