Transcriptome profiling of Nudix hydrolase gene deletions in the thermoacidophilic archaeon Sulfolobus acidocaldarius [PDF]
Frontiers in Microbiology, 2023 Nudix hydrolases comprise a large and ubiquitous protein superfamily that catalyzes the hydrolysis of a nucleoside diphosphate linked to another moiety X (Nudix).

Low Salt Influences Archaellum-Based Motility, Glycerol Metabolism, and Gas Vesicles Biogenesis in Halobacterium salinarum [PDF]
Microorganisms, 2022 Halobacterium salinarum NRC-1 is an extremophile that grows optimally at 4.3 M NaCl concentration. In spite of being an established model microorganism for the archaea domain, direct comparisons between its proteome and transcriptome during osmotic ...

Towards a molecular picture of the archaeal cell surface [PDF]
Nature CommunicationsArchaea produce various protein filaments with specialised functions. While some archaea produce only one type of filament, the archaeal model species Sulfolobus acidocaldarius generates four.

MinD proteins regulate CetZ1 localization in Haloferax volcanii [PDF]
Frontiers in MicrobiologyCetZ proteins are archaea-specific homologs of the cytoskeletal proteins FtsZ and tubulin. In the pleomorphic archaeon Haloferax volcanii, CetZ1 contributes to the development of rod shape and motility, and has been implicated in the proper assembly and ...

MinD2 modulates cell shape and motility in the archaeon Haloferax volcanii [PDF]
Frontiers in MicrobiologyIn bacteria and archaea, proteins of the ParA/MinD family of ATPases regulate the spatiotemporal organization of various cellular cargoes, including cell division proteins, motility structures, chemotaxis systems, and chromosomes.

Evolution of Archaellum Rotation Involved Invention of a Stator Complex by Duplicating and Modifying a Core Component [PDF]
Frontiers in Microbiology, 2021 Novelty in biology can arise from opportunistic repurposing of nascent characteristics of existing features. Understanding how this process happens at the molecular scale, however, suffers from a lack of case studies. The evolutionary emergence of rotary

The infection cycle of the haloarchaeal virus HFTV1 is tightly regulated and strongly inhibits motility of its host [PDF]
mSystemsAlthough viruses have been shown to infect all domains of life, our understanding of the genetic program behind the exploitation of host resources to produce progeny virions is thus far limited to several bacterial viruses.

Two different sulfotransferases modify sugars of the N-linked tetrasaccharide decorating Halobacterium salinarum glycoproteins [PDF]
mBioDespite providing the first example of archaeal N-glycosylation almost 50 years ago, detailed insight into the pathway used by Halobacterium salinarum to assemble and attach an N-linked tetrasaccharide decorating glycoproteins in this haloarchaea has ...

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery. [PDF]
Mol MicrobiolThe Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.
