Towards a molecular picture of the archaeal cell surface [PDF]

Nature Communications
Archaea produce various protein filaments with specialised functions. While some archaea produce only one type of filament, the archaeal model species Sulfolobus acidocaldarius generates four.

MinD2 modulates cell shape and motility in the archaeon Haloferax volcanii [PDF]

Frontiers in Microbiology
In 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.

The infection cycle of the haloarchaeal virus HFTV1 is tightly regulated and strongly inhibits motility of its host [PDF]

mSystems
Although 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]

mBio
Despite 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 ...

The nucleotide-dependent interaction of FlaH and FlaI isessential for assembly and function of the archaellum motor [PDF]

Molecular Microbiology, 2016
The motor of the membrane-anchored archaeal motility structure, the archaellum, contains FlaX, FlaI and FlaH. FlaX forms a 30 nm ring structure that acts as a scaffold protein and was shown to interact with the bifunctional ATPase FlaI and FlaH. However,

Horizontal gene transfer of the functional archaellum machinery to bacteria

Motility in archaea is driven by a nanomachinery called the archaellum. So far archaella have been exclusively described for the archaeal domain, however, a recent study reported the presence of archaellum gene clusters in bacterial strains of the SAR202

Nitrosarchaeum haohaiensis sp. Nov. CL1^T: Isolation and Characterisation of a Novel Ammonia-Oxidising Archaeon From Aquatic Environments. [PDF]

Environ Microbiol Rep
Following a 3.5‐year enrichment cultivation period, a rapid‐growing ammonia‐oxidising archaeon, designated CL1T, was isolated from the East China Sea. Strain CL1T represents a new species within the Nitrosarchaeum genus and is capable of effectively oxidising ammonia at both low and high concentrations through the GS‐GOGAT and GDH pathways. Furthermore,

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A. [PDF]

mLife
Abstract In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and chromosomal DNA import, respectively.

Cellular and Genomic Properties of Haloferax gibbonsii LR2-5, the Host of Euryarchaeal Virus HFTV1

Frontiers in Microbiology, 2021
Hypersaline environments are the source of many viruses infecting different species of halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce, due to the lack of genetically accessible virus–host models. Recently, a new

Living electronics: A catalogue of engineered living electronic components

Microbial Biotechnology, Volume 16, Issue 3, Page 507-533, March 2023., 2023
Biology leverages a range of electrical phenomena to extract and store energy, control molecular reactions and enable multicellular communication. Recently, the microbial machinery enabling these redox reactions have been leveraged for interfacing cells and biomolecules with electrical circuits for biotechnological applications.
